Hi team,
I am planning to upgrade from the OS 2.1 to 2.4 with the information below: 02 virtual ISE, running in HA mode; each node has PAN, PSN and MnT.
I will do the upgrade procedure like that:
- Running the Upgrade Readiness Tool.
- Backup all the configuration / certificates / keys on both Nodes
- Upgrade the Secondary Node.
- Upgrade the Primary Node.
I have the qns below:
- do we need to break the HA mode between the Primary Node and Secondary Node before doing the upgrade? After doing the upgrade successfully on each node, we will re-join the HA mode.
Or we can do the upgrade on the Secondary first and the Primary later.
Highly appreciate for any quick response.
Thanks in advance.
Br,

I would do the backup and restore method vs. trying the upgrade process.
You can certainly attempt the upgrade process, but the rebuild/restore method is guaranteed success. I have only started using the Cisco upgrade method for 2.3 and later.

During the software upgrade, it automatically deregisters the node and moves into a new deployment.
No need to manually break the sync. Also, you can upgrade the secondary first and the primary.
Please follow the upgrade guide
