Currently when a user updates/adds a table to a portlet and increments service.properties, the upgrade process will backup, upgrade, and restore all data for all models tied to that portlet.

We need to improve this so the upgrade is smart enough to just:

1. only update the tables that have been changed
2. add new tables if there are those found
3. should only backup/restore data tied to the tables that have been modified
