What is Data Migration ?Definition,strategy and best practices

Data migration is the process of transferring data from one storage system to another. It can involve moving data from one physical storage device to another, such as a hard drive to an external drive, or moving data between different software systems, such as transferring customer data from a spreadsheet to a customer relationship management (CRM) system. Data migration can also include taking backups of data and archiving old or unused datasets. Data migration is important for businesses who want to keep their information organized and up-to-date.
