I would like to test the transition from 2.x to 2.5 on a backup machine we have. Am I correct in believing I can simply move the data files over and point the 2.5 server at them?

The only note I found on this was this:

Which appears to detail problems in one particular file. But I can't tell from context if this is a general issue or applies only to the USERs.
