Hi,

Our Critical Database is implemented on Oracle 11gR2 11.2.0.3 Single Instance DB with Oracle Data Guard Standby DB.

We want to upgrade to Oracle 11gR2 RAC 11.2.0.4 in a New 2 Node Envcan't upgrade now to !2c as application is not supported)

I have thought of 2 options to upgrade:

Option 1

  1. Install 11.2.0.4 RAC in 2 New DB Servers
  2. Install 11.2.0.3 in one of the DB Server (Node 1)
  3. Backup and Restore DB from Prod to DB Server Node 1 (recovery not required as we will use Offline Backup)
  4. Start DB in 11.2.0.3 Env
  5. Upgrade to 11.2.0.4 using DBUA in 11.2.0.4 env

Option 2

  1. Install 11.2.0.4 RAC in 2 New DB Servers
  2. Backup and Restore DB from Prod to DB Server Node 1 using RMAN
