8.    Data-intensive migration projects require technical expertise and cross-functional support throughout the project lifecycle

9.    One of the first steps is determining what kinds of data need to be included in the project

10.    Approach selection – Determine which approach best suits your needs from a service provider perspective

Systems development life cycle (SDLC) strategies can help you keep track of data during a migration project. They also provide guidelines on how data should be managed throughout the process.

During the data migration project, it is important to maintain a detailed inventory of all source and target system information. You must keep track of all changes made to your systems and locations so that you can properly plan for the future.

Data migration may be necessary when moving to SaaS, public cloud, or private cloud applications. At times it could be an alternative to business process re-engineering (BPR). It involves 

IT & Data analysis – key stakeholders are identified, requirements are gathered, business processes are analyzed

Understanding existing systems - including their constraints, limitations, etc.,

Developing new processes based on subjective needs

Planning for data conversion and reconciliation

Tools for data migration: For data migration projects, you need to select the right tool or combination of tools that can address your specific business needs. These include Data Conversion & Transformation Tools (ETL Tools), Data Replication & Synchronization Tools, Database Loading/Extraction Tools, REST API Interoperability Solutions, etc.

Migration concerns during cloud computing: Migrating to the cloud brings its own set of challenges - security facets are one of the primary issues that businesses will face while moving their data to the cloud. You must consider how sensitive customer information is handled by different services providers before signing on with any of them. The other areas where you need to focus on specifically are whether or not all of your data is encrypted in the cloud and how secure it is, and about the location of your data: in which part of the world will your data be stored? All these concerns must be considered seriously.

Families within Cloud Computing: Cloud computing can exist in different forms and we group them into four primary families: Private/Enterprise Cloud, Public Cloud, Community cloud & Hybrid Cloud


Provides IT services to a single organization

It has dedicated resources or multiple vCPUs offered across trusted or geographically dispersed locations. It provides maximum control over the security & privacy of information. The infrastructure and OS are optimized for consistent performance and processing time leading to efficient use of resources like compute, memory, disk space & network


Provides IT services to multiple customers across the globe. It can be public or private. A cloud provider manages these resources which are shared across many customers and they charge on a pay per use basis

Their infrastructure is scalable both vertically & horizontally according to your needs. Their advantages are - Platform agnostic, Doesn't require any maintenance of hardware/software, No upfront investment in infrastructure, etc.


Is a new way for service providers to achieve economies of scale by sharing hardware, software & other IT resources among different organizations with common interests who trust each other. They are kept isolated from each other. The term 'Community' implies that the organizations are specialized in certain fields/domains, have a common interest in collaboration & share resources with each other


It is a combination of private cloud & public cloud. It allows you to use the benefits of both technologies like On-premise servers and storage can be used to host private clouds and public cloud(s) can be used for additional capacity when it is required. Information can be shared between on-premise and public or community clouds etc.

Why is data migration considered difficult and risky

Migration of data from one system to another is considered difficult and risky because of the big size of datasets, which makes it time-consuming. Also, data may have been accumulated over some time and all this information needs to be converted into a new system. Not transferring some part of data can lead to information loss causing major problems for businesses.

What are the different types of migration tools

There are many tools available for migrating and integrating cloud systems: Database conversion and synchronization tools: Make database conversions between two database systems by mapping tables, rows, and columns across relational databases. ETL (Extract & Transform Load) Tools: ETL tools simplify complex data transformation processes with minimal programming as they allow users to use a visual interface to design and schedule data transformations. Data synchronization tools: Provide a unified interface for mapping, copying, transforming, and monitoring data across on-premise and cloud systems. Application Portability Tools: With these, you can develop specific connectivity solutions between cloud applications to transfer complete or partial application elements such as files (.e.g., spreadsheets), database components (tables, records), Web services (methods, messages), or UI screens. Batch Transfer Tools: These are used for the simultaneous transfer of a large number of records from one system to another in small batches rather than transferring one record at a time. Batch processing reduces the overhead of repeated authentication & security-related activities which are performed while transferring data element by element

What are the different types of data migration

There are two types of data migration: 1. Top-down approach 2. Bottom-up approach In top-down, the existing data is kept intact and a new set of code is written to port or copy that information into a new environment In bottom-up, the old system(s) are replaced by a new one(s) and all the content from these systems need to be migrated to it This type of migration may not always be possible as this involves rewriting any outdated/legacy program codes depending on the technology being used for development   

What are some prerequisites before migrating to the cloud 

Some prerequisites required before migrating your business applications to the cloud are: Business needs well defined so that you can investigate and analyze the pros and cons of cloud deployment. Identify application-related activities that could benefit from cloud deployments or where it is not possible to use a cloud platform. Lead time required for setting up & configuring your operating system, databases, etc., should be considered as well as how complex this setup is since such factors will affect the cost of migrating. Leave some slack time to perform testing when migrating applications in phases

How does data migration impact security

There are different types of security involved in data migration depending on the nature of the business being migrated:

Privacy Security  - This includes confidentiality, access control, authentication controls

Audit Security - It records what has happened in an environment so that auditors can determine whether all required actions have been performed.

Availability Security - It ensures the availability of data to authorized users at all times   

What are some methods used for cloud integration

Cloud integration involves sharing information between clouds. Here are some different ways this can be done:

Database replication & synchronization Tools: Synchronize data between two databases so that users always have access to up-to-date information. Data Replication tools: these automatically pull changes from a source database into a destination database without human intervention or any gaps in the historical record Data federation tools: Combine distributed datasets residing on multiple platforms, applications, and middleware products. These tools allow you to integrate databases without having to move or copy data Integration brokers/adapters: These connect distinct systems by acting as a go-between, passing data from one to another using standard protocol such as Enterprise Application Integration (EAI)   

How do you choose the right cloud solution for your business

The first step is to understand your business needs and come up with a set of requirements Business model - Ensures that your business model supports cloud computing. This means deciding whether you will create a public, private, or hybrid cloud. Infrastructure costs must be reduced so that value can be obtained from the cloud Adequate & skilled workforce – Businesses need to have employees who are trained well enough to work in an environment that uses cloud systems as technologists designing and building such solutions need expertise in network security and user access controls Implementation time - The amount of time it takes to deploy a system into a cloud environment Using an established Cloud services vendor - While you might be tempted to build your solution, this is generally a costly and time-consuming process that can end up being more difficult than expected     

How does data migration impact the performance of systems

In some cases, migrating data to a new system can improve performance. For example, if there are bandwidth limitations between two computer systems or the hardware needed for the application has been upgraded. In other cases, it may affect performance because users have become accustomed to working with faster response times from legacy systems   

What is data migration

Data migration is fundamentally moving data from one location to another. Migrating data ensures that the data remains available and accessible even as systems and platforms evolve and grow. There are different types of data migrations:

Application Migration - moving software and associated data from one platform to another

Database Migration - moving all or some of a database's content, including table structure, data values, metadata, etc., into different storage devices

Infrastructure Migration - transferring hardware devices along with associated infrastructures

Operations Systems/ DBMS Migration - This involves migrating the operating system running on the equipment used for an application without fully replacing it   

What are some considerations for cloud security   

Before deploying any applications in the cloud, assess your business' security risks. Consider the security implications of user access to cloud resources, authentication requirements, data storage/retention policies, and more Cloud computing services are subject to the same technical issues as other technologies, including network attacks. But cloud computing adds new types of technological risk including persistent malware attacks

What happens after the migration process is complete 

Whether it's a full or partial migration, implement tools to monitor any ongoing activities in real-time. This helps ensure that all systems are performing properly at all times   

What are some challenges associated with cloud implementation  

Because cloud implementation involves organizational change management across multiple departments—not just technical implementation—it can be difficult for an organization to realize success without effective planning and communication A lack of cloud computing knowledge and expertise is a huge hurdle, as many organizations simply aren't familiar with the technology and how to implement it successfully   

What is a cloud automation    

By automating repetitive tasks, your team can spend more time focusing on higher-value work. The more consistent you can make processes, the more consistent your data will be as well Automation helps bring down labor costs because the same task doesn't have to be completed over and over again In addition, some cloud migration strategy tools have built-in features that let you automate certain aspects of the process   

Cloud Migration strategies & Integration – Data Migration is a complex process that requires expertise in project management, network security, and user access controls. Before deploying any applications in the Cloud, assess your business' security risks. Know that technical implementation may be challenging without the right planning and communication.

Data migration vs. data conversion vs. data integration

Data migration involves transferring data from an old system to a new one. A data conversion, on the other hand, often involves translating data into a different format with similar semantics. Data integration—in which systems are linked together so that information flows between them—is closely related to both of these tasks.

Data migration techniques

Data migrations often rely on different techniques, such as data replication and real-time synchronization between old and new databases. This process may involve extracting the data from the source system, cleansing it, transforming it to meet the requirements of the target system, loading it into a staging area, verifying its accuracy against the source system's stored logic rules (Business Rules), then finally moving it into production.   

What are some cloud security considerations

Cloud computing services are subject to the same technical issues as other technologies, including network attacks. But cloud computing adds new types of technological risk including persistent malware attacks. Before deploying any applications in the cloud, assess your business' security risks by considering things like user access cloud resources, authentication requirements for access, data storage/retention policies, and more

What are some challenges associated with cloud implementation

Because cloud implementation involves organizational change management across multiple departments—not just technical implementation—it can be difficult for an organization to realize success without effective planning and communication. A lack of cloud computing knowledge and expertise is also a huge hurdle, as many organizations simply aren't familiar with the technology and how to implement it successfully.   

Data migration process

Involves extracting, transforming, and loading data from a source system to a target system. The process may involve using transformations to bring data up-to-date, converting the data into formats that work best on the target platform, or creating copies of databases from one environment for use in another.

Why do we need data migration software

Data migration software helps automate the conversion of multiple data formats into a single, standard format for ease of use within new or existing systems. Data migration tools also help resolve issues with complex data structures and facilitate the verification of migrated data

What is a common challenge when migrating from mainframe to cloud

A common challenge associated with migrating from a mainframe to the cloud is changing how applications are updated. In a traditional environment, updates to an application may be made on-premises using physical media that contains updated code. This process would then need to be tested before being rolled out into production. In a cloud environment, this type of delivery method isn't possible due to security concerns and administrative limitations.   

How can you manage all your applications in the cloud

Managing all applications in the cloud requires you to have a strong understanding of existing technology and how it can be used within your overall IT strategy. Cloud computing services are subject to the same technical issues as other technologies, including network attacks. Adopting a single cloud platform may simplify this task, depending on an organization's unique needs.

What is the benefit of migrating from the mainframe to the cloud

When migrating from a mainframe environment to the cloud, an organization can improve security by moving its data into a managed hosting environment that offers greater protection against unauthorized access and exploits. In addition, organizations can take advantage of cost savings compared with maintaining on-premises hardware and software licenses as well as reduced administrative costs, because cloud providers handle routine system maintenance.   

What are the three main components of successful data migration

A successful data migration depends on several factors, including having a well-designed project plan in place for coordinating efforts among stakeholders, migrating data in manageable chunks to avoid overwhelming employees with a large volume of updates all at once, and ensuring that everyone involved in the process understands any changes in procedures that will occur as part of the move.   

What is on-premise software vs Cloud-based software

On-premise software is installed locally on your computer or server whereas cloud base software runs on another companies servers. This allows you to access the application via an internet connection rather than downloading it to your local device.  

NetApp and data migration

NetApp is committed to helping organizations on their cloud journey by providing the trusted storage, systems, and data management solutions needed for success. We understand that as customers adopt new cloud strategies such as infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS) technologies, they need guidance on how best to build a complete data center solution. By working with a single partner who offers a broad portfolio of enterprise storage and big data solutions spanning compute, networking, and virtualization – all at globally competitive prices - your organization can realize business value from its investments in the public cloud. NetApp has been at the forefront of developing many of these technologies, including on-premises cloud storage, hybrid cloud integration, Cloud IQ analytics, and FlexPod. Find out how you can transition to NetApp for all your data center needs.   

What is Cloud IQ

CloudIQ is a market-leading technology that provides the tools needed to power real-time insights into tenant activity in multi-tenant clouds across private and public deployments. It's purpose-built for today's leading clouds including AWS, Microsoft Azure, VMware vSphere, OpenStack, Hyper-V, etc., so you can get more value from your existing infrastructure platforms without having to replace them. It also delivers workload portability between these infrastructure cloud environments allowing tenants of any size to move their mission-critical applications seamlessly between multiple IaaS platforms.

CloudIQ continuously captures and analyzes workloads as tenants move them across infrastructure platforms, monitoring for compliance with internal policies and external regulations such as HIPAA, PCI DSS, SOC 2/3, FedRAMP, etc., generating real-time alerts to facilitate forensic investigations into security incidents and helping companies optimize their cloud costs by quickly identifying any usage inefficiencies and oversubscription.   

How does data migration work

Data can be migrated from the mainframe to the cloud using a variety of tools including SaaS migration systems designed specifically for migrating applications and databases to IaaS clouds such as AWS or Microsoft Azure. Data can also be exported out of existing on-premises systems as flat files before it is uploaded to the cloud. Migrating data involves extracting it from existing systems, transforming the format of that data into a compatible format for the new system, and then uploading it into that system.   

What are some business benefits of data migration

Migration is key for most businesses who want to take advantage of both on-premise and cloud computing power. The main benefit is businesses take advantage of more powerful tools in the cloud without having to purchase any additional hardware or software. Another major benefit is being able to pay only for what you use with IaaS vs investing upfront inexpensive servers which can lead to higher initial capital expenses (CAPEX) versus operational expenditures (OPEX). This relieves business owners from worrying about over-purchasing hardware and software which can lead to wasted spending on redundant systems.   

Datacenter migrations

On the other hand, are more complicated processes needed to move massive amounts of data from one data center to another. Data centers are typically located in different parts of the country or world with many being housed near major cities where they're able to connect directly into larger telecom networks. You can think of your mainframe as your top-level data center that is mainly responsible for enterprise-level computing needs such as databases, storage, and security. This data center needs to be centrally located so all users across an entire organization can access it; otherwise, it will create downtime and slow down activity across the business which could negatively impact productivity.   

What are three ways I can migrate

There are three primary ways you can migrate data from your mainframe to the cloud:  

1) Ingest - Ingest is a data migration technique used for cloud computing that involves moving large amounts of information from an external source into a data center. It can be used as a means to transfer data from on-premise resources into the cloud over wide area network links or internet connections. During ingestion, logs and other generated files can also be processed to remove sensitive information so it's no longer included in the final migration package which reduces risks associated with data security breaches.   

2) Export - The second method for migrating mainframe data is called export. This process involves exporting mainframe data out of its existing archive locations either locally, regionally, nationally, globally, or virtually as flat files. Exporting out of a mainframe system is often used as a precursor to extract data from the mainframe's sources and then re-import it into Oracle or other relational databases that can host cloud applications.   

3) Replication - The final method for migrating mainframe data involves replicating the entire source database through a virtual private network (VPN) or other remote access software to create a replica of your on-premise database in the cloud. This process essentially makes a local copy of your entire database by using advanced replication technologies to transmit real-time updates directly from one site to another without any lag time, downtime, or disruptions which enable you to maintain always available operations even if a disaster were to strike the primary data center.   

How do I know which method is right for me

All three methods can be used to successfully migrate mainframe data into the cloud, each with its unique benefits and drawbacks. When deciding which option best fits your business needs here are some questions you should ask yourself:  

1) Which systems need to be migrated?

2) How much time do you have to achieve this migration?

3) How much information is there that needs to be transferred?

4) Does the size of the data impact risk or security concerns?

The answers to these questions will help determine how you proceed with migrating mainframe data into the cloud. For example, if you only have a few days before downtime occurs then you should go with replication or ingesting. However, if you have plenty of time then exporting mainframe data into the cloud is usually the best option. Lastly, if your total amount of data is relatively small and there are no risk factors involved, then this will most likely be the ideal method to use.
