Re: 11gr2 s/w install

RAC these days consists of two installations. 1) "Grid" software which includes both clusterware and ASM 2) "Database" software in a separate directory

You can only have one active grid installation on a server. You could install it to a different directory than the old clusterware, but you cannot have both running together - you'd have to shutdown the old before starting (or even installing) the new. There's no automatic method for "failback" (re-activating) the old grid home, but with some caveats and work this might be possible (until you update ASM on-disk data structures).

You can have as many active "database" software directories as you want. You can have 11.1 running alongside 11.2 running alongside 10.2. The clusterware and asm layers are fully backwards-compatible, meaning that all of these different versions of the database software running at the same time on the same server will use the single 11.2 clusterware and ASM software.

Hope you're able to do the upgrade - it's a great learning exercise!
