[Zope] Migration problems

[John Poltorak]

I spent some time looking at Zope several months ago but because of the 
steep learning curve gave it a rest after a week or two, but would like to 
get back to where I left off. Unfortunately I seem to be unable to access 
ZODB now after having upgraded Python, Zope, CMF and Plone.

I presume I need to migrate whatever objects I built previously to the new 
environment... Is there any guide to doing this?


Here is the sort of error I get when trying to start Zope:-

Traceback (most recent call last):
  File "/usr/local/zope/lib/python/Zope/Startup/run.py", line 49, in ?
    run()
  File "/usr/local/zope/lib/python/Zope/Startup/run.py", line 19, in run

  File "/usr/local/Zope/lib/python/Products/ZCatalog/Catalog.py", line 17, 
in ?
    from MultiMapping import MultiMapping
ImportError: filename doesn't match module name


Where do I start in trying to sort this out?
