[Zope] CMF import issue

[Talha Haroon Attar]

Hi

I imported a CMF site into my zope installation from another zope
installation. I have the 2.6 version while this site was installed on
2.5.1 version. Plone extensions are used in the site as well. Although
my import was successfull I could not import a lof of objects including
ones under portal_skins/Images and many others. Also the site does not
seem to function on my installation. Is there something I should know of
here?

Appreciate your reply
