Is it possible to uninstall the Tridion SP1 HR#1 hotfix from the CMS and leave the DB Updates in place? We experience very slow behavior of the GUI since applying the hotfix (maybe related to TMS service failing?) and need to go back to SP1 – however, we have made content updates to the DB since we applied the hotfix and would like to know if SP1 is compatible with the HR#1 DB Updates.
I realize this is a very specific issue – but maybe someone else has needed to rollback to SP1 for a different reason?
There is no supported way to roll back the upgrade nor is there a supported way to run an older version of the product on a newer database.
The closest you can probably get is restoring your database backup and install a plain SP1 on a new box. This is one of those cases where having a virtualized environment would help, since then you could probably roll back to your previous snapshot of the VM (similar to how you restore the database).
