I installed UMP 2.5.1 several months ago but have not put it into producton yet as we have had considerable issues with our Nimsoft database. I see that 2.5.2 is out and think I will upgrade to it before putting it into production. I am curious about the upgrade. On the download page it says to backup your UMP implementation before upgrading and that it modifies the database.
What database is it modifying? Is it modifying the Nimsoft SLM database or it's own LifeRay database on the UMP machine itself?
