During an upgrade from 6.2 to 7.2, the DB Upgrade Tool was run against a 6.2 Database. The upgrade tool itself ran to completion, without any errors, but starting the bundle in 7.2 resulted in having no portlets deployed.

In discussions with Alberto Chaparro, we believe the best path forward might be to just throw an error in the event that this happens again, so that it can more easily be addressed.
