Data Migration is the transfer of data from an incumbent database to its replacement. The process is consultative in nature and usually involves programmers and subject experts deciding how to convert (or 'map') records from the old system into the new, then writing scripts or programs to automate this. In some cases (where the system is very old, obscure or the volume of data is small) it may be easier to re-enter records. After successful data migration, the original system usually ceases to be in use. Contrast with systems integration which involves the sharing of data between two live databases systems that will both remain operational.
