I have always ran multiple versions of oracle on a single server with
many databases. You are upgrading both OS and Oracle at the same time.
I recommend moving your databases to free up a server, upgrade the OS on
that server then migrate the databases to free up another server.
Upgrading an OS and Database at the same time is risky business.

Tracy:
This is just silly. If you're working for a company that can buy a
separate server for every single installation of oracle, that company
is making too much money.
Any DBA that EVER crashed a db due to "administering db in an
incorrect manner" ought to have their sorry butts fired.
I've had occasions where, for a variety of vendor-related reasons,
I've administered up to 5 different versions. It's a reality of our
business. I've never experienced a problem runing multiple versions.
I'm currently running 5 databases with 7.3.4,
5 databases with 8.1.7.4, and 4 databases with 9.2.0.4, all on the
same server, and all are running just fine.
Just my .02, but you should stick to your guns.
