Hi, I'm planning to convert (migrate) a entire site from php3 to zope and i'm looking for suggestions, hints, etc on this. It's a GPL management school system done in php3+postgresql, and any user must be authenticated against a database and his privileges are those from the postgresql. The system is in portuguese (www.univates.br/sagu) if someone is interested. Does somebody have experience in such kind of migration (conversion) and can give me some "in advance" advice to avoid this or that or don't do this, etc, etc? Any comments?
