Database migration with physical standby database

edited Apr 12, 2017 5:24PM in High Availability Data Guard, Sharding and Global Data Services (MOSC) 5 commentsAnswered

Our current production database server is solaris t4 running oracle 11.2.0.4. It has hot standby database using ADG in DR data center.

We would be migrating  our production database  to  solaris T7 alongside T4 . Since oracle version is going to be the same, I would be also using ADG to replicate database to solaris T7.

So 11.2.0.4 running on solaris T4 would have 2 standby databases :

11.2.0.4 running on T7

11.2.0.4 running on T4 on DR data center

During cutover, I plan to do role switch - T7 database would become production  database and T4  would be become standby, to be decommissioned later.

What would happen to 11204 database in DR datacenter during the process of migration.  Do I have to rebuild it to synchronize it with 11204 on T7

Howdy, Stranger!
