How to rename a vCenter in NetWorker?

Hi! 

I was approached by a customer, that they are planning to rename their vCenter server in the next few months. I did some tests with my lab VCSA (FQDN & CNAME pointing to same IP). But I didi not manage to keep the "old" backups that were taken with the old vCenter name. Save sets still there, but  not visible in Restore wizard.

Here is what I did:

1. configure vCenter with FQDN & create some vProxy backups.
2. Remove the entire vCenter config (delete vProxy, VM group)
3. Rename the vCenter client object. (create client with CNAME & clientID from FQDN)
4. configure vCenter with CNAME

After this, I can successfully run backups & I see the Save Sets that were backed up using the FQDN now belong to the CNAME. That was expected.

But when I try to restore a backup using NMC restore wizard, I can only see the backups that were taken after the renaming of the vCenter. Each VM shows up 2 times (but same UUID) and no matter which one i choose, the old backups are not shown anymore.

Has anyone ever solved this?

Any help is highly appreciated.
