=============================================================================
The main AE database contains tables with name MQ1CP001_UCORIG.
Release : 21.0.0 Component : UTILITIES
This is a bug in the 21.0 DBLoad Utility
The main database contains tables called MQ1CP*_UCORIG which are detected by the utility during the upgrade.
This has been fixed with the release of 12.3.9 and 21.0.3
Two workaround exist to perform the database upgrade successfully:
-- Removing all tables MQ*CP*_UCORIG from the main AE database again and run the load again.
-- Edit the DBLoad upgrade script UC_UPD.txt from the version 21, remove the lines "MIGRATE_TO_SEQUENCE" and run the Reload again.
