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
