Migrating Printers from 2008 r2 server to 2012 r2

Hello,

I'm trying to make as small of a user impact as possible for a print server migration to servers with different names.

I've successfully exported printers from a 2008 r2 server and imported them to a 2012 r2 server.  I then removed the 2008 r2 machine from the domain.   After the DNS record removed, I made a CNAME for the 2008 r2 machine to point to the 2012 r2 server.

When I try to print using a printer installed from the 2008 r2 name, I get print spooler errors.  Am I missing an SPN command to make this change work?  Or should I be taking a different approach?

Thank you
