Dear all , I am planing to upgrade an IC 4500 Active/Passive cluster from 4.4R8 to 5.0R1 . Any one have a procedure to do so ? do i need to break the cluster first ? What about the NAC client , Automatique Upgrade is possible ?
No special process required. Just update the primary node in the cluster and it will automatically upgrade the other node once the primary has completed the upgrade.
