CTGKS0163E Migration fails. The database schema version could not be set to 2.0 to indicate successful database schema and data migration during the previous migration attempts.
At the end of migration, the migration program sets the version to 2.0 in the database to indicate that the schema has
been upgraded to the latest level. It also drops the migration-related table from the database.
The database server might have stopped. Start the database server and run the migration again.
