We are planning on going to OES11 (mixed bag of OES2, Netware 6.5) doing a server consolidation project, the new OES11 box will be 2 OES11 servers connected to a SAN with Cluster Services.
The services we plan on utilising are NSS, iPrint, CIFS, AFP

However we are going to wait until OES11 is suported by Symantec Backup Exec. So the plan is to use the new hardware with Novell Cluster services on OES2SP3 - 32BIT. Once OES11 is suppoered by Backup Exec, Can I then do a rolling cluster upgrade to OES11 - 64 Bit. I've nevered used Cluster services so unsure of what are the limits.
