Recently I had to move a Zope (Plone 2.0.x) instance, and I have found
that I can't just move the Data.fs. It stores several absolute paths
that become broken if the paths of the things (like of some files in
products) changes. So finally I have exported the objects (PloneSite
objects), and imported them into the new instance. It worked, however
then the user name of the last modifier of the objects was replaced with
the name of the user who did the importing /-: (while the last
modification date has remained intact -- strange). (Also, I seems one
have to be careful to create the same users in the /acl_users than in
the old instance, otherwise the exported stuff will have some strange
security errors.)
