[Zope] 2.5.1 to 2.8.0

I have a Zope install 2.5.1 that I am wanting to migrate to another box that has 2.8.0. After the 2.8.0 install I import the .zexp's and copy the data.fs file from the old var to the new. This never goes successfully as I get the following when pointing to localhost:8080/manage and after I authenticate: Zope Error Zope has encountered an error while publishing this resource. Error Type: AttributeError Error Value: getItem Can anyone let me know what I might be doing wrong? I have stopped and restarted zope after making the changes. Thanks, Tim
