I upgraded vCenter Server 7 license to 8, but I'm still using version 7. What to do now?
I can downgrade license, but would I get old key back or would I got a new one? If I got a new one, then probably should change it on vCenter.
Also what is the best way to get key for version 8 if I want to use it in parallel with version 7?
Check the version of your ESXi hosts if they are compatible to vCenter version 8 then upgrade your vCenter to version 8. By doing this you can also manage the ESXi hosts having the latest version.
If you have 1 vCenter license you can run only run on licensed instance at whichever version. However if you don't license the new one you can run it with full functionality on the 90 day eval key. Is this long enough for you to decide whether v8 works for you? Don't vCenter v8 will support both v7 & v8 ESXi hosts.
I know that, but key was for more than 1 instance. So I divided upgraded license and then downgrade one of two new licenses. Hope it's compliant, support didn't get me undoubtedly answer.
