# rke

Hi guys, I am using RKE 1.3.11 and I need to move my cluster nodes interfaces IPs from 172.16.30.x/24 to 172.16.40.x/24. They are VMs so I could change easily their IPs but I guess I can not just happily change the IP's in the cluster.yaml file and expect it works next time I run 'rke up'. The first thing I think will fail is the cluster conectivity because the IP in the api certificate will not match, but probably there will be way more things to take in care. Can anyone throw some light on how to change the IPs of the cluster nodes? Any help or clus is welcome. Thank you in advance
