We're about to embark on a journey to upgrade our two Enterprise, v8.0.0 servers (which are currently synchronized) to the latest version (10.1).
I've checked out your upgrade guides and rollback guides and it all looks pretty straight forward, however most of the information looked like it was for single server environments. I couldn't see any information that related to upgrading a cluster.
Are there any additional steps we need to take, or special order in which to do things? We'd like to keep at least one server up at all times so we don't have any downtime/outages.
Thanks in advance.
