[Zope] Upgrading Zope instances from 2.5 to 2.6a

[Gitte Wange]

Hello,

I am trying to upgrade one of our instances from Zope 2.5 to 2.6a ...
We are running the instance using INSTANCE_HOME so I have just started
to Zope-2.6 with this instance home ..

But I get the following error:
2002-09-23T14:01:00 ERROR(200) Zope Couldn't install BackTalk
Traceback (innermost last):

index_object
  Module ZODB.Connection, line 533, in setstate
SystemError: Failed to import class Splitter from module
Products.PluginIndexes.TextIndex.Splitter.ZopeSplitter

The error appears for all the products.
Looks like something has changed in PluginIndexes ?
:-)

What should I do in order to correct the error ?
