[Zope] Migration of Zope 2.2.3 Installation

[Segedunum]

Hi All,

I've got a server that is running Zope 2.2.3 (currently using Python 1.5) that 
I need to migrate, and I'd appreciate some advice.

Given some cyclic dependencies on this system we can't upgrade Zope straight 
away, but we need to upgrade the rest of the system which indirectly entails 
updating to Python 2.4 which is unavoidable. Does Zope 2.2.3 depend tightly 
on Python 1.5, or could it run under 2.4? If not I'll have to think about 
some kind of slotted install and move over.

Just wondering if there any issues people have encountered in upgrading pretty 
old Zope servers that may be helpful, such as migrating the Data.fs (this is 
pretty large).

Thanks,

David
