You may need to do surgery on your old userfolder here:  it is the
'groups' object in that method, and apparently has a 'has_key' method
but not a '__getitem__'.  I would set a breakpoint in the
'old_validation' method and watch it fail.

If you look at the user folder(s) in your site via the ZMI, what type
are they?  (they will have the name 'acl_users' in their folder).

For any package in the old server's $SOFTWARE_HOME/lib/python/Products:

 - If a package with the same name is in the new server's
   $SOFTWARE_HOME/lib/python/Products, that means that it shipss
   with Zope itself;  you should not need to do anything.

 - Otherwise, try copying the old package into $INSTANCE_HOME/Products.
   You may have to update or patch the copied products to get them to
   work under Zope 2.10.
