Same Veritas Cluster different versions of linux

Hi, I know yet that you can't run different versions of veritas cluster.

But, I you have different versions of the operative system?, for example Linux - Linux or Linux and windows..

RedHat 5.9 to Redhat 6.2 (same version of vertias cluster) can I run a two node cluster?

RedHat 6.2 and SUSE 11 (same version of vertias cluster) can I run a two node cluster?

Redhat 6.2 and Windows (same version of vertias cluster) can I run a two node cluster?

I am sure that it is impossible get support of this, only for migration proposes.

Regards!
