Can Rman be used to migrate a database from a 32 bit environment to a 64 bit environment? Would this work: 1) Take an RMAN full backup of the database 2) Build a 64 bit machine 3) Install 64 bit O/S and Oracle. 4) recreate the exact same folder structure as on the 32 bit machine. 5) Login to RMAN and do a redirected restore. I have a 9.2.0.8 database. Have to make sure that 9.2 is available in 64bit. If not, I would have to upgrade to 10g. Thanks Bob
