Can you help me to find the best method how to upgrade 10.2.0.4 to 188.8.131.52 with physical standby database, in my opinion :
1. Stop applying redo log
2. Stop all standby service
3. Upgrade standby
4. Switchover to upgrade standby
5. Upgrade old primary if no error in step 4
Please give any suggestion to best method and minimal downtime, and note i have more 4TB data, thank's.
