Upgrading the UGC database
If you have UGC (User-Generated Content) installed as a standalone product alongside SDL Tridion 2011 SP1, upgrade your existing Oracle or Microsoft SQL Server UGC database by running a PowerShell script.
Before you begin
To install or upgrade SDL Tridion databases on a Windows machine requires Windows PowerShell 3.0 and Microsoft .NET Framework 4.0 or higher.

What to do next
If you encounter problems during the upgrade, restore your backup and try again. If your second attempt fails as well, consult SDL Tridion Customer Support for assistance. Do not attempt to fix the database.
