Hi ,

We need to upgrade database from 11g to 12c . 11g db is in one data center and other one in different dc.Please let us know if below plan seems to be good.

1. Install 11g binaries at target and build  dataguard (Physical standby).

2.do failover/switch over  and convert standby as primary.

3. stop source db 11g for backout plan.

4. upgrade standby db from 11g to 12c which has been converted as primary .

or

1. create restore point.

2.switch over to standby and make it primary.

3.upgrade standby  from 11g to 12c.

4.restore source db from restore point  for the backout plan in case something goes wrong.

Howdy, Stranger!
