Groupwise 2012 server is being moved from a Server 2003 to a Server 2012.

We have a virtual server with eDir (8.7) that serves as the master, and the existing 2003 server (with Groupwise 2012) as a replica. Can we move our Groupwise 2012 to the new server hardware and install the Novell client rather than install eDir? We will be upgrading to 2014 in 45 days.
