Thanks, I'm aware of the backwards compatibility and in one of our datacenters we run 11g clusterware managing a 10g database. We are looking at another datacenter where we want to minimize the downtime to upgrade the clusterware and db by using Streams to a new RAC instance. I was just wondering if it were possible to have the separate clusterwares running on the same box using isolated accounts. I didn't have high hopes for it so I thought I would throw it out to the list to see if anyone has ever tried it.  I appreciate answers that say "no it wont work" but I really love answers that say why it wont work and give personal experiences from those that have tried to play around with it.

Thanks all. It looks like I will just Stream off elsewhere.
