Change subnet

Visitor

we have the usual vnet setup with a/24 subnet split into /25 for vms and /27 for DMZ and /27 for Bastion. the users were running out of IP addresses for VM deployment. I have setup a vnet with a /24 subnet which can give them more IPs but, they want the bastion to be enabled for accessing the VMs. I made sure the VMs are turned off and tried changing the subnet /25 but it says it is in use,. Does Azure allow changing the subnet? I know I can add a whole new subnet for bastion but, I'm thinking about the possibility of changing the same subnet for keeping it organized.

You can, but need to remove those VMs from the Subnet first. Then return after making the change
