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.

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.
