Moving a VM system containing 1 vCenter server and 2 ESXi servers to new IP segment without downtime possible?

Dear Experts

I need to move a VM System containing of 1 vCenter server and 2 ESXi hosts to a different IP segment.
Is there any way to achieve this without any downtime (a HA cluster is configured - vMotion).

According to this post (https://www.experts-exchange.com/questions/28371304/Moving-VCenter-server-to-Data-center-from-10-200-x-x-to-10-100-x-x-network.html) this should be my checklist more or less, but it requires downtime:

Change IPs on Physical/VMs
Disable HA on cluster
Remove ESXi hosts from vCenter
Change IP of vCenter
Change IPs on ESXi hosts
Add hosts to vCenter

Does anyone know of a way to do it without any downtime?

Hello Andrew

Thank you for your reply.

Is the checklist above correct?
This is the first time doing a change like this so I just want to make sure I get it right.
If you have any more points to add to it or any additional points to add under each point (links etc) it would be very helpful.
Yes, the order is correct.

It's a fairly simple procedure.
Dear Andrew

In order to remove the hosts from vCenter, you need to put them into maintenance mode and subsequently power them off.
Not normally. vCenter Server is just a management platform.
