System and method for migrating databases

Abstract:

Some embodiments provide a non-transitory machine-readable medium that stores a program. The program receives data from a subset of a first set of exchange tables stored in a first database of a source system. The program further creates a second set of exchange tables in a second database of the device. The program also creates a set of shadow tables in the second database of the device. The program further adapts the second set of exchange tables and the set of shadow tables to a higher upgrade version. The program also performs object generation based on the second set of exchange tables and the set of shadow tables. The program further drops the set of shadow tables. The program also receives a set of application tables from the source system. The program further adapts the set of application tables to the higher upgrade version.
