+1 for sure for what Heiko recommended

Plus, first place:
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Cluster_Administration/ch-overview-CA.html#s2-newfeatures-6.3-CA
and links

I remember some problems passing from 6.1 to 6.2, because I had
virtual machines configured as cluster services.
If it is your case, the first place to search for vm compatibility is
the table 4.1 at
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Administration_Guide/Live_migration_and_RHEL_compatibility.html

See also my thread about clvmd problems I'm facing in 6.3 (but it is CentOS)

Also these pointers could help in evaluation:

and previous and following posts of the thread

HIH,

PS: share your clvmd in 6.3 experience then, it you have it... ;-)
