Looking for tips and best practices for upgrading OEM 10.2.0.1 to
10.2.0.5 on an 8 core Sun v490. It's currently monitoring about 60 hosts
and 140 databases, some of which are critical production systems. I want
to keep the down time to a minimum. Does anyone have an idea of how much
down time is necessary to perform such an upgrade?
I've thought about installing anew on a 2nd host and migrating the
monitored hosts one by one to the new OEM but there are *very* many
firewall considerations in my environment and that itself will become a
large project. Do you think this is the best approach?
TIA
