Granwille,
Your understanding is correct.
If you want to assign the same IPs back to the original VMs you need to add the
new network as additional NIC to the same VMs then change the new network to
default and remove the old one.

Subject: Re: Moving Multiple Shared IP ranges from one Guest network
Hi Jithin
Thank you for getting back to me. Sorry, that came out wrong I make use of
Advanced and not basic zone. That said, I am not sure I understand the
following:
Identify the IP range VR uses that needs to be retained in the network
Change IP to the one range that you want to retain.
Since my network has three subnets that are being used by VMs and one VR, do I
understand correctly that I need to leave one range in place, the range that is
tied to the VRs public IP, yes? And then, for the other two ranges, after I
have stopped VMs and changed their IPs I can remove those two ranges and create
two new networks for each range. Will I then be able to assign the old IPs back
to the VM afterwards?

Hi Granwille,
So you are using a basic zone and you have multiple subnets for the
‘defaultGuestNetwork’ in the same pod?
You want to create new guest networks right, but that is not possible in a
basic zone. You could add a new pod and add the new subnets there but within
the same guest network.
If you are using an advanced zone with shared network you can follow the below
steps:
Stop VM
Identify the IP range VR uses that needs to be retained in the network
Change IP to the one range that you want to retain.
Goto VM->NICs -> change IP
Once you change the IPs for all the VMs you should be able to delete the range
from the existing network and create a new one.

Subject: Moving Multiple Shared IP ranges from one Guest network
Hi Guys
I have basic private cloud setup. I have one guest network that contains three
shared public IP subnet ranges consisting of /28 and /29 ranges. I have been
recently advised that it would be better to make a guest network for each
subnet range instead of having them all under one network.
The issue is, I already have VMs assigned to those public IP ranges and they're
currently running. What would be the best way to solve this? Can I just remove
the ranges from the existing network and quickly add a new network with those
ranges and have a new VR boot up? Would it then continue to run on the existing
VMs? I reckon I need to have the VMs stopped first in any case, yes? Also, I
have ZERO API experience so this needs to happen all via UI.
