Has anyone manged to complete a SLES based ZCM 11 to Windows ZCM 11 transfer?

Our main Primary with the certificate on is a SLES 11 box but we need to migrate to Windows; can you just add a Windows server to the same zone and then move the certificate across using the ZMAN tools? Or is it more complicated than that? We have to remove SLES from our portfolio ASAP.

Novell's advice seems to be mixed as to whether it is supported or not.
