Hey guys,  
i’m running a two-node HA cluster with SLES 12 SP5 and two HP servers.  
We will now exchange the old server with a new one. How to achieve that ?  
My idea is:  
move all resources to the newer server  
delete the old node from the cluster  
shutdown the old node  
install and configure the new one with the same HA configuration as the old one  
start the new one, start pacemaker and integrate it into the cluster  
Is that ok ?  
What if additionally i’d like to update the OS of both with SLES 15 ? Is there a way ?  
How would you do that ?  
Thanks.

Bernd
