Upgrade to Veeam 12 question

[Ultra_VM]

Hi we are on Veeam 11 and vCenter / ESXi 7.03 and moving to Veeam 12 and vCenter / ESXi 8.03

Whats the best to update first ?

Veeam 11 to Veeam 12
or
vCenter 7.03 to VvCenter 8.03

If vcenter to 8.03 first should I update the ESXi to 8.03 too before Veeam 12.

I raised a ticket with Veeam but the answers are just links to articles and not clear as to what to do. (07836425) [Moderator: Replaced Support ID with Case ID]

Thanks

Upgrade Veeam Backup & Replication first, or you won't be able to backup VMs on vSphere 8.0.3.
