1. Any advise from anybody who has performed an inplace upgrade from Oracle 10gr2 to 11gr2 involving 3 or more RAC nodes ? We were told that this was not advisable ?
2. We were also informed that it is not possible for two RAC instances having different versions (11r2 and 10gr2) to co-exist in the same servers under RAC ? Is this true ?

well as per my knowledge you can have two different oracle versions in a RAC and if u read about cluster services ,so one of service is responsible for management of comptability issues among nodes in RAC having different oracle versions .sorry didn't remember that service name.
