How do I import sites from one farm to another

Feb 28, 2013 at 4:15 PM
I'm trying to export/import sites between farms using stsadm. When I do so I get some errors that might be from having this feature installed.

I'm migrating from a WSS 3.0 farm to a MOSS farm. I have deployed the feature in the moss farm.

The error I get is "length cannot be zero". I'm not sure it has anything to do with your feature but wanted to see if there is a certain migration path I need to take.
