What is Data Migration?

Data migration is the process of transferring data between storage types, formats, or computer systems. Data migration is usually performed programmatically to achieve an automated migration, freeing up human resources from tedious tasks. It is required when organizations or individuals change computer systems or upgrade to new systems, or when systems merge.

Term Data Migration is most commonly used on several different operations which are of complex nature

Data Migration is always process of balancing between cost of risk and complexity

Examples of Data Migration methods with a focus on process performance and service availability

Steps of Data Migration process

Data Collection for the needs of migration design

EMC GRAB tool for the UNIX OS systems

EMC REPORTS tool for the Windows OS systems

HEAT reports – for comparing hosts with EMC InterOp matrix

SWAT reports – for comparing SAN with EMC InterOp matrix

Outputs of these tools is needed for the creation of the design and having an overview of the current infrastructure
