Upgrading to a new version may have version specific issues or
As each new version contains new and improved bridges, you should update models only if

existing database models harvested as single models with previous versions using the
Migrate to multi-model databases
available at the model or directory level from the repository manager.
This operation converts a single database model into a multi-model database. It
includes the migration of the database documentation, connection stitching, and involvement on
data flow and semantic mapping.
