Cause

When DevTest is upgraded to a new version , schema upgraded.  But, when the components  with earlier version of DevTest  were started , it caused 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 configured 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.
