How to replace a host in Vcenter with 3 licenses already used?

Hi everyone!.. This is my Scenario:

VMware vCenter Server 6 Essentials (3 host) ---->vCenter Server

VMware vSphere 6 Essentials (3 host)  ---> Host1 - Host2 - Host3

Host1 is an old DELL R710 and we bought a new DELL R740 (Host4) server to replace them

I need:

Migrate the virtual machines form Host1 to Host4, then eliminate Host1 from vCenter and add Host4

I can't add the host4 to vCenter first to migrate the virutal machies because vCenter Essential only licence 3 host (already taken)

Thanks a lot!

What may be an option is to:

  1. temporarily remove one either host 2, or host 3 from the vCenter Server environment
  2. add host 4 (in evaluation mode)
  3. migrate VMs from host 1 to host 4
  4. remove host 1
  5. assign the free license to host 4
  6. add the other host back to the environment

Is it possible for you to migrate the Host 1 VM's to host 2 and host 3 and remove the host 1 from VC??

Hi. thanks for your fast answer.

It's impossible, because the 3 host are at 90% ram Smiley Sad

How about to install a new Vcenter with temporary licence... add the HOST4... and HOST1... and move the Virtual Machines?

Should work?

So in that case you need to take the server downtime.

Present the datastore to new host and shutdown the server on host 1 >> remove from inventory. Connect to the host 4 and register the virtual machine. Once all the VM's powered on host 4 remove the host 1 and add the host 4.

But if you are using DVS then it will create problem!!!

Are you using iSCSI/FC or local datastore?

Ohhh!!! So in this case you need to perform V2V of the virtual machines to new host.
