Hi,
We want to transfer our prod DB's to new exadata machines with minimal downtime.
Currently we have Primary A and Standby B that are on machines A and B.
To move the DB's to new machines C and D with minimal download we thought about the following :
1.Create secondary standby C on machine C (A will be primary, B and C will be standby)
2.Create on machine D standby instance D to the C DB (C will be primary, D will be standby)
When moving to new prod we cut the standby connection between A and C and point all the users to work on C DB.
