I have a wikiweb that has all the change history since its inception available to users. I want to export this to a new Zope installation without losing this information. How do I do this? Not sure, whether you can follow this line. But it would probably be the easiest way:

You start with your old "Data.fs" in the new side and there, you delete everything you do not like.

No can do. I have some sort of corruption in the ODB that becomes apparent when I try upgrading (see trace below). On top of this I don't want to drag around the history of everything else in the ZODB. How hard would a selective pack operation be? ie pack everything but one folder

An alternative may be an external Python script that uses XML-RPC to fetch the versions of an object in the source Zope and create/update them in the destination Zope. It would need an External Method in the destination to tweak modification time and friends. Not too easy...

hmm, sounds complicated. Actually sounds like ZODBReplication or synchronization. Can you outline in a little more detail how you would do this? How do you tweak the modification time etc? --------------- http://azonia.auslabs.avaya.com:9080/manage_main gives <p> Error type: SystemError<br> Error value: Failed to import class Guard from module Products.PythonMethod.zbytecodehacks.VSExec </p> <p><a href="http://www.zope.org/Credits" target="_top"><img src="http://azonia.auslabs.avaya.com:9080/p_/ZopeButton" width="115" height="50" border="0" alt="Powered by Zope" /></a></p> </BODY></HTML> <PRE> Traceback (innermost last): File D:\Zope\AUSLAB~1\lib\python\ZPublisher\Publish.py, line 223, in publish_module File D:\Zope\AUSLAB~1\lib\python\ZPublisher\Publish.py, line 187, in publish File D:\Zope\AUSLAB~1\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File D:\Zope\AUSLAB~1\lib\python\ZPublisher\Publish.py, line 171, in publish File D:\Zope\AUSLAB~1\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_main) File D:\Zope\AUSLAB~1\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: manage_main) File D:\Zope\AUSLAB~1\lib\python\Shared\DC\Scripts\Bindings.py, line 324, in __call__ (Object: manage_main) File D:\Zope\AUSLAB~1\lib\python\Shared\DC\Scripts\Bindings.py, line 354, in _bindAndExec (Object: manage_main) File D:\Zope\AUSLAB~1\lib\python\App\special_dtml.py, line 236, in _exec (Object: manage_main) File D:\Zope\AUSLAB~1\lib\python\DocumentTemplate\DT_In.py, line 670, in renderwob (Object: objectItems) File D:\Zope\AUSLAB~1\lib\python\DocumentTemplate\DT_In.py, line 765, in sort_sequence (Object: objectItems) File D:\Zope\AUSLAB~1\lib\python\ZODB\Connection.py, line 533, in setstate SystemError: (see above)
