I have a situation where I am failing back from azure using modernized site recovery. I had in my lab notes that the vcsa 'friendly name' that you supply when registering must match what the friendly name was in my old azure appliance. Can anyone confirm? I am just trying to be cautious as we reverse replicate the servers, many thanks in advance.

    Hello Tyler Saville

    Good day!

    In your case, I see the VMs have been failed over to azure under ASR and you are in a situation where the on-premises vCenter server appliance has been rebuilt?

    Ideally if you have rebuilt the VCSA with same name and IP address, and shown as registered in the recovery services vault. The failback will work without an issue. S

    This has been mentioned in the following section of document https://learn.microsoft.com/en-us/azure/site-recovery/vmware-azure-prepare-failback#reprotectionfailback-components

    In general, If you failed over a VMware virtual machine, you can fail back to the same source on-premises virtual machine if it still exists and CS is available. In this scenario, only the changes are replicated back. This scenario is known as original location recovery. If the on-premises virtual machine does not exist, the scenario is an alternate location recovery.

    So, it depends if it detects that VM has same UUID in new vCenter. I would suggest, you can try out one VM re-protect from Azure to on-premise and see the behaviour.
    Good luck!
