Hi,
I have a working implementation for Zope 3 ZPTs within Zope 2. It is currently implemented through a new class ZPT which implements the same functionality as Products.PageTemplates.ZopePageTemplate. I am currently thinking about the migration to the new implementation. Would it be possible to perform an in-place migration using setstate() when replacing the ZopePageTemplate implementation with the prototype code from my ZPT class?
Are there different object-attributes in both classes? If not, you could simple replace with the same old class name. If there are (you would have to know them anyway to do the __setstate__ approach) I'd like an approach with an upgrade script (similar to 'stale Python Scripts') better. Buts just me ;-) Regards Tino
