I am preparing to upgrade our current vSphere 6.5 to 7.0. We currently have a single 6.5 ESXi host running on an HP ML350 G6 server, and vCenter Server is running on a Windows 2016 VM on a Hyper-V host.
I have installed ESXi 7 host on a new HP DL360 G10 and plan to migrate the existing 4 VMs on 6.5 to the new host.
I understand vCenter on 7.0 is now only a linux VM, but it appears that it MUST run on a ESXi host, not Hyper-V. This concerns me because I learned a few years ago that it’s impossible to install updates on an ESXi host when the vCenter is on the same host, which is why it is now on Hyper-V.
Is this true, and does that mean I need at least 2 ESXi hosts to ugrade to 7? If not, how do I install vCenter or VCSA on the single host and still do updates?
Thanks in advance,
