Trying to migrate to plone 2.1 failed ("migration did not reach this point"). Limi suggested a forced upgrade from 2.0.5, which shows the error below. See for more details.

Severity: normal => serious

Objects get copied around during migration, and the zwiki page(s) get activated in such a way that they recreate their outline object behind the back of the migration code, confusing it.

likely workaround --simon, Mon, 29 Aug 2005 22:51:27 -0700 reply

Use the ZMI to move your wikis out of the plone site, migrate it, then move them back.

alecm has checked in a fix in ATContentTypes?, also I am including a fix in Zwiki. Either of these should resolve the problem, so either upgrade your Zwiki to 0.45 or greater, or upgrade to the next plone release when it comes out.

fixed in zwiki 0.45 or plone 2.1rc3 --simon, Thu, 01 Sep 2005 15:04:55 -0700 reply
