Currently at one of the DC, they have vCentre 4, so all their
ESX are of version 4 or lower.
However, I'm selling ESXi V5 to them & the customer wanted
us to help upgrade the vCenter to Ver 5.
Is upgrading of vCenter from Ver 4 to 5 is something free or we need
to purchase a licence?
Kindly provide step by step instruction on how to do this upgrade,
where to download Ver 5 & any prior backup (using Acronis)
needed? I think the customer's vCenter is running as a VM.
Let me know any precautions needed? During upgrade of vCenter,
will it affect the ESX other than there's no monitoring? What if I
clone the vCentre 4 so as to leave the current running vCenter
alone while I upgrade the 'isolated' vCenter VM to vCenter 5
(with this VM not connected to network). How do I go about doing
this, step by step.
Pardon me, I have no skill in VMware/vCenter other than ever
login once to a couple of VMs
