We have a new Dell FX2 server chassis with 4 FC640 blades installed that will be taking over for 4 Dell R620 1U servers. In total we have 8 VM hosts, 4 will be replaced this year and the other 4 will be replaced early next year.
I have the new ESXi hosts up and running and manually configured each hosts networking and storage for the time being, just to run some test loads. Now I'm at the point where I am ready to add them into vCenter 6 server for management and convert their networking to dV switch and start vmotioning VM's to them and decommissioning the old ESXi servers. VMWware gives you 60 day fully functional trial licence so I can get this done well under 60 days thanks to vMotion. Then when I remove the old hosts I can assign those licence keys to the new hosts. Finally when done I will want to rename the remaining hosts so that all servers are numbered in order. Going from a vm1, vm2, vm3, vm4, vm5, vm6, vm7, vm8 naming scheme to vm01, vm02, vm03, vm04, vm05, vm06, vm07, vm08. The new ones are already named properly so I just have to rename the remaining 4 hosts that are staying with us for another year.
My question is how will this affect Veeam licencing? Will the backups continue to operate, or do I need this completed in 1 business day so that it still sees the same number of overall cores present in the vSphere infrastructure? Once new hosts are added, and then existing hosts renamed, does anything need to be done in Veeam? Or will it just learn of this from vCenter?
Thanks for your help!
