In place upgrade CentOS 7 to UBUNTU KVM clusters

Hello,

We are planning to replace our CentOS 7 hosts with latest Ubuntu LTS server
and we want to keep all existing keys, hostnames, ips e.t.c

When testing with one host we get the following message which is expected:

java.lang.IllegalArgumentException: Can't add host: repl1 with hostOS:
Ubuntu into a cluster,in which there are CentOS hosts added

Any ideas how to proceed from here ?

Thanks,
