Upgrading HA Active-Passive Cluster
Hello,
soon i have to upgrade an 200D 5.0.9 Active-Passive Cluster to 5.2.2 .
Should i realy follow the steps described in the HA Doc? like just push the upgrade on the Master unit and he will do all the job by himself?
what are your experience upgrading a cluster? should i better first upgrade Slave per FortiExplorer and after that upgrade the master ?
Thanks
