I followed the HOW-TO here http://www.zope.org/Members/mcdonc/HowTos/zopeinstall/ZOPE-INSTALL-HOWTO And looked around for different documentation but, alas, was left without much help. I can move over the Data.fs file, and reinstall the products but every product is broken when I start it back up (again and again). I have tried removing them and reinstalling them but it will not let me import the .zexp files (any of the products). I get the following error (for more than one product) Error type: SystemError Error value: Failed to import class _ZClass_for_ZPhotoAlbum from module Products.Photo Traceback (innermost last): File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_importObject) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_importObject) File /usr/local/zope/lib/python/OFS/ObjectManager.py, line 519, in manage_importObject (Object: Traversable) File /usr/local/zope/lib/python/ZODB/ExportImport.py, line 208, in importFile SystemError: (see above) Even products that there is no .zexp file like SimpleURL 1.0 the product is just broken. Is there another way of going about this? Anyone done it successfully? I guess my next step is to try out each and every one of these products in Zope 2.2.2 to see if they actually work. Thanks, J
