vSphere Essentials upgrade from 4.1 to 5.5 and move to vCenter Appliance

Hi,

I'm in the process of planning to upgrade from vSphere Essentials 4.1 to 5.5.

Currently I run vCenter on Windows 2008 R2 but want to remove the complexity and OS licensing costs associated and thus deploy vCenter Appliance instead

I know you can't migrate my old vCenter settings to the new 5.5 vCenter Appliance.

So whats the process to move to the 5.5 vCenter Appliance?

1) Shutdown old vCenter Windows VM

2) Startup 5.5 vCenter Appliance and set with same IP as old vCenter VM

3) Configure vCenter Appliance adding in the existing 4.1 hosts (not sure if I have to remove the hosts from the original Windows VCenter as the 1st task?)

4) Apply 5.5 new licensing for vCenter + hosts (maybe the old 4.1 hosts won't accept the 5.5 licensing until upgraded?)

5) Upgrade hosts

6) Update VMWare Tools

Any help on the correct approach would be much appreciated

Thanks

Keith
