Chris, I purged the database of its transactions and took the data.fs as a whole from the old zope to the new. This installed properly. Only one product was missing (coreblog). This appears to have caused the problem. When I removed this from the .zexp file there was no problem importing the file. Like some other products from the old version this probably needs to be reinstalled in the new manner (I installed a new zsql methods product from pypi with easy_install). Thanks, anyway. Henk this is the traceback of the original error: Traceback (innermost last): Module ZPublisher.Publish, line 126, in publish Module ZPublisher.mapply, line 77, in mapply Module ZPublisher.Publish, line 46, in call_object Module OFS.ObjectManager, line 619, in manage_importObject Module OFS.ObjectManager, line 637, in _importObjectFromFile Module ZODB.ExportImport, line 92, in importFile Module transaction._transaction, line 253, in savepoint Module transaction._transaction, line 250, in savepoint Module transaction._transaction, line 647, in __init__ Module ZODB.Connection, line 1104, in savepoint Module ZODB.Connection, line 564, in _commit Module ZODB.ExportImport, line 175, in _importDuringCommit Module None, line 22, in<module> Module None, line 57, in<module> Module None, line 44, in<module> Module None, line 38, in<module> Module None, line 39, in<module> ImportError: No module named ThreadLock Op 28-8-2011 20:15, Chris Withers schreef:

I have a zope server 2.10.2 running. After upgrading to a 2.13.4 version of Zope and importing a .zexp folder from the old version I get the import error: No module named ThreadLock. In version 2.13 the module ThreadLock was removed it states in the changes description. What can I do to make it work again?

A good start would be to post the full traceback relating to the error to this list.

cheers,

Chris
