Zusammenfassung:	A system for database migration including one or more processors and one or more memory devices storing instructions The processors are configured to perform operations for database migration that include cloning the online database to a first clone database, generating export files from the first clone database and importing them to a migration database, performing a row comparison of the first clone database and the migration database after importing the export files, and initializing a double write operation replicating writing of the online database on the migration database to capture incremental data. The operations also include cloning the online database to a second clone database after performing the row comparison, identifying catch-up data by comparing the second clone database with the incremental data, and updating the migration database to include the catch-up data.
