From what i have researched so far, RMAN does not support duplication (i am not talking restore here, but duplicate clone) between different version of oracle. So if you have a very critical system, then obvious thing to do would be upgrade dev, then test , then production. But let's throw another complication into the picture, if lot of your dev and test instances are refreshed from production RMAN backup on a daily basis. Then you can't really upgrade dev/test first and leave production, until your testing is finished. RMAN does not allow duplicating a database from older version to newer version. Though there is a procedure to restore database and then upgrade/downgrade eg. restore database; recover database; alter database open resetlogs upgrade/downgrade; now follow the downgrade/upgrade steps; As anyone found any way of duplicating database using RMAN from say 10.2.0.3 to 10.2.0.4?
