We need to change subnets of VRA’s and our ZVM’s. What is the proper sequence or recommended actions for doing this?
I’m not associated with Zerto but we are going through something similar here as a cloud service provider. To my understanding the procedure would be as follows.
This is what I have gathered would be the process for our environment.
@Zerto if you can add additional insight to the steps above it would be greatly appreciated to myself as well.
The main reason behind this question was we had the VRA’s and ZVM’s on the same OTV enabled subnet so when we had a circuit blip the replication failed due to network asynchronous routing issues until the ISP network back failed back or it was restored. I think as long as we can re-ip the VRA’s to a new non OTV port group I should be okay to leave the ZVM’s in the OTV port group and replication will continue the next time we have a network blip or circuit failover. Just as long as there is still IP connectivity between them.
@Zerto if you can add additional insight, KB’s, or confirm my working theory that would be great.
