Hi everyone,
Our old CPPM servers are going EOL in April so we purchased new ones to upgrade them. I'm wondering what the best or simplest approach is to swap the existing gear out. We have to keep the same IP addressing scheme as the current ones so that limits us to having a parallel environment of any kind.
My thoughts were to stage each one in our lab with just login credentials and the same IP address. Then we would unplug the old one, plug the new one into the switch and then complete any finishing touches before joining it to the cluster.
If the above makes sense, is there a process to doing this like upgrading the subscribers first and then the publisher or doing the publisher first (by promoting another subscriber to become publisher first)?
Thanks for any suggestions or tips.
