I am upgrading a 6 node cluster from 6.0 sp5 to 6.5 sp3 and am looking
for some very detailed documentation on what happens during a rolling
upgrade. This doc (http://www.novell.com/documentation/oes/index.html?
page=/documentation/oes/cluster_admin/data/al3oeqd.html) gives me an
overview but I have some questions about
1. Once I upgrade Server1 can I migrate resources back to that server
before the last server is upgraded?

2. When the Media Manager is called to upgrade disk media what is
really happening? I have 15 resources with a total of 3.5 Terabites of
storage. How long will(should) this take?

I'm trying to develope a good plan and be overly cautious.
