Auto top off tool

Abstract:

Systems and methods for the migration of large amounts of time-varying data from a source database to a target database are disclosed. After completion of an initial long-duration migration, a validation is performed to determine if any groups of data were updated in the source database during the initial migration. Updated data is then topped-off by migration to a temporary container before merging into the target database. Subsequent validation can confirm that migration is complete or initiate one or more additional top-off migrations.
