I have an issue with our SRX240 firewall cluster. Due to oversight in the upgrade process, our secondary node was left running JUNOS 11, and our primary running 12.1X46-D40.2.
I have a remote console on both units and shipped a USB drive out there with 12.1X46-D40.2 on it. Should this be as easy as disabling the HA and the uplink ports on the secondary unit, rebooting it, and bringing up HA and the uplinks? I don't want to overcomplicate this, but I do want to make sure i'm picking the best course of action.
Thanks in advance!
