Hello everyone,
In my company with have a cluster of 5 Clearpass servers with some latency between servers.
Yesterday we tried to upgrade the cluster manually from 6.7.13 to 6.8.5, I mean one server at a time. Not with the "cluster upgrade" function because of the latency between servers as I said.
However, when we did manual upgrade on the publisher from 6.7 to 6.8.5, the server's declustered and we lost all licenses so we rolled back.
Moreover, when we installed the firmware and rebooted the publisher, the server booted on 6.7.13 instead of 6.8.5. In order to boot on 6.8.5, we had to do it manually in CLI with the command : system boot-image.
A solution for this issue ?
What do you recommand about this upgrade from 6.7.13 to 6.8.5 ? The best practises for the smooth running of the operation.
Manual upgrade on each node, or "cluster upgrade" ?
Thank you in advance for your time.
Regards,
Rayane
