What ESXi versions can I manage with vSphere 4.1

Hi Experts,

I am running vSphere 4.1 managing ESXi 4.1. If I want to upgrade to ESXi 5.5 can I still manage it with vSphere 4.1?

No. ESXi 5.5 cannot be managed by vSphere 4.1

VMware's interoperability matrix is where you can find this information:


In your case, in the solution section I entered 'VMware vCenter Server' Version '4.1' and under Platform/Solution VMware ESX/ESXi.

This will provide an easy to read matrix. A green check mark/tick mean compatible, none means not.

You will need to update to vCenter Server 5.5.

vCenter Server 5.5 can manage 4.0, 4.1 and 5.5 hosts.

You will also need valid ESXi 5.5 and vCenter Server 5.5 licenses.
