Any in-place upgrade can cause issues to arise.  The BEST method of 
dealing with an upgrade is to run a test instance of (in your case, 
3.2.3 with all local mods and perform an upgrade on it.  See what issues 
arise and fix them.  Make copies of all your fixes, and repeat the 
procedure on your real install.  That said, I have never had a problem 
beyond having to re-create some local mods because different versions 
can have API changes which broke them.

The best upgrade "how-to" is the README.
