Jim has written a generations module which looks like a promising framework to deal with implicit migrations in a sane way. -aj pgpilPy98CwYt.pgp Description: PGP signature ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

If export/import does not work between given Zope versions, it is quite likely that the same Zope versions will have difficulties with storages exchange -- and this *IS* a migration issue, Zope should be concerned with (and not the applications). If it does, export/import will simply follow (in most cases). -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Possibly we are talking about different things. A most common mistake of Zope especially Plone users is to think that export/import acts as a migration tool (export your Plone 2.0 site on system A and reimport it into a Plone 2.1 installation on system B). This does usually never work when the internal data structures have changes (you know that :-)). Supporting such migration support for Zope core was/is always a goal since we have the app (Zope) in our hands but we can not sell export/import as a universal migration tool. 3rd-party apps have to deal with that. -aj pgp5Md1HrQ98W.pgp Description: PGP signature ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

[Zope] Error importing objects 2.8 2.7
*Been working up some code on a zope 2.8.0 install, and I wanted to move it over to a live server.
