I am looking at upgrading my current IDM 3 environment to 3.5. I
currenlty use the VAULT which in turn connects to an AD, NT and Edir
production tree. My question is :- is there any gotcha's about the the
upgrade process or is it just as easy as runnning the setup routine????????

I don't have the luxury of having a test environent to test first :-(

Help much appreciated.
