I need some advice on how to upgrade a 4510R+E switch with 2 x WS-X45-SUP8-E modules without any downtime?
The reason is it came with a non k9 ipbase software and I would like to install the same version but with k9 ipbase.
The license is correct and is ipbase so there should be no license issue.
Thanks in advance!
VSS upgrade, using ISSU, FSU/eFSU, would work if each downstream device is dual-homed.
