What problems, specifically, are you referring to? I've been using
Europa-created workspaces with Ganymede for at least 6 months now
without any problems. In fact, I can even switch between Europa and
Ganymede running against the same workspace and it seems to work just
fine (even though that is not officially supported).

I can't say exactly what problems can be, I just read many times in the
newsgroup that it is suggested to create a new workspace and import the
old projects rather than starting with a new version of Eclipse on the
same (old) workspace. I remember this was particularly true for WTP
projects. Maybe WTP 3.x is perfectly backward-compatible with WTP 2.x,
but anyway I would always prefer to start with a new fresh workspace.
Mauro.
P.S.: I just found out an old discussion in eclipse.tools.jdt newsgroup,
titled "sharing java projects among 3.3 and 3.4 workspaces". In that
topic JDT developers say that, for JDT, "Moving forward is supported
i.e. you can start a 3.3 workspace with 3.4 but if you start a 3.4
workspace with 3.3 unexpected things can happen and hence that scenario
is not supported.".
