Thanks Dan. You picked up immediately as to where I was going with this,
and yes, we are using VMs, at least at first, to build test and validate
various upgrade scenarios. Saying whether this could be done or not
without going the VM route definitely is the answer and saves us some
time...

This is why I use VMs (even for RAC/clusters)--for testing upgrades,
resetting to the old version and repeating until it goes well.

Our thought was that we could use nodes (in a test scenario only) running
different versions to practice upgrades and migrations of databases from
one release to the next.
Of course, if this works in practice, it would offer less downtime in
production upgrades, right (similar to staging a single-node upgrade by
installation of software only in advance).
