I forgot to mention that there is no connection between the old and new datacenter. If there would, I would just present the new SAN space from the new datacenter to the old one, so I can just add the new OCR/Votting disk to the current ones (mirror) and then remove the old disks.
Same for the ASM and databases, but unfortunally, there is no connection between this two datacenter.
It is like moving the servers from one state to another.
Use RMAN and Data Guard to create a physical standby in the new data center.
Fail over to the new data center.
Turn off the lights at the existing location.
Move the OCR and Voting Disk? I wouldn't touch it.
No connection between the data centers? Get one for 30 days.
Unfortunately, I don't have another physical server to implement the solution you are proposing.
are you going to have same ip addresses/subnets for public / private interconnects? The steps you have mentioned looks ok. If the ip addresses are different, you need to update the cluster config with oifcfg commands. You will be able to find that information on the oracle support.
For sure your steps are prone to error while restoring at the other data center. Plan another way.
Share your experience here if you already started the process.
Fortunatelly, yes. No changes on the ip addresses.
That is exactly what I am looking when I post here. Check what other options do I have if the proposed one is not good.
If you have RAC you either have two physical servers or you have a disaster waiting to happen: Which is it?
If you have two physical servers ... move one ... turn it into a DG standby ... fail over to it ... then bring over the other server and do an ADD NODE.
Yes, I have a 2-nodes RAC.
I have not experience using Data Guard. I have read about the Standby/fail-over feature but I was not sure that if will work with RAC (OCR/Votting disks).
Could you please tell me where I can find more information about Data Guard standby setup for RAC?
Please refer below link for 11g RAC datagard setup,
And compared with RAC ... Data Guard is very easy to implement.
