Hello Team, We have a Morpheus production appliance with
3 Node HA running on RHEL8
External 3 node Percona XtraDB cluster
Current version: Version 5.4.12.102
We are planning to upgrade the appliance from 5.4.12.102 to the latest LTS version 6.2.2. I would like to ensure 6.2.2 version is a stable one and are there any known issues that we should we aware of. Also we are current running on 5.4.12.102 i.e. with a WAR deployment(a fix for one of the Morpheus nightly jobs for cost) and do we need to follow any specific upgrade instructions other than the one highlighted in
https://docs.morpheusdata.com/en/latest/getting_started/maintenance/upgrades/3node/rpm.html#node-ha-centos-rhel-upgrade
Ours is a sensitive environment that cannot afford downtime as all the mission critical application VM and DB provisioning are automated through Morpheus. Hence wanted to take a well prepared risk free approach for this upgrade.
Appreciate your guidance/insights in this regard.
Thanks a lot.
