I have been trying to understand the upgrade process for what I am running
now. I am currently clustering vm's on ocfs with oes2 sp3. I want to upgrade
to OES11 and continue using it the way it has been setup. Novell has
suggested this as the easiest solution to upgrade the the oes2 sp3 vm's I
currently have running. I understand that I have to install HAE during the
upgrade. My concern is what will happen after the upgrade with 2 different
version running in the cluster. Should all the vm's remain down while
upgrading all 3 hosts to OES11 during the upgrade? Will there be any gotchas
after the upgrade?

Thanks
