Briefcase path not the same after a migration.

[dsiminiuk]

After a server migration from Ubuntu 12 to 14 using ZeXtras, objects in the briefcase have a different URL than the original server. I don't think all the LDAP parms were migrated and that's ok, but I have reconfigured with zmprov for Public Service Host, Public Service protocol and Public Service port but the ERROR 500 messages in the preview pane still says "service/home/user@" in the error message. The original server has /home/user@ (the "service" part is missing from the path). I do not have memcached or imapproxy installed on either machine.
When I try to preview or edit any Briefcase objects I get this error
HTTP ERROR 500
Problem accessing /service/home/user@domain.com/Briefcase/History. Reason:
Server Error
