Cause:

When DevTest is upgraded to a new version and used the same DB but for some reason when the components were started with earlier version of DevTest causes the Schema upgrade issues.

Environment:

All Supported DevTest Environments.

Resolution:

Once migrated to the new version, the schema is changed to new version of DevTest and no earlier releases of DevTest can be started to go against that database again. This is by design.

Need to drop all of the DevTest tables on the DB and have them created again. Once the tables are dropped, start the Registry again and all of the tables will get re-created.
