Greeting

I have a XOA with 4 hosts (XCP-NG) and all contain a number of running VMs

Now I need to change the management IPs of those Hosts as well as XOA

Do I need Down Time or is it easy? can do it without any effect on the customer clients.

I can access the hosts through direct connection (vga,keyboard), I do not know how important management IP is in this.

please advice before I start changing the IPs
