CIsco ISE 1.2 to 1.3 upgrade

[abhishek.marat1]

I am planning for an ISE upgrade from version 1.2 to 1.3. I have two nodes (primary admin, secondary monitoring (ISE 3355) in one box and secondary admin, primary monitoring in the other (3315).) and 8 PSNs (all 3315).

My question is after upgrading when we are testing for failover of the HA pairs in both the nodes…are we going to face any technical complications because of the different model numbers. All nodes (2 +8= 10) are in different locations.

I don't believe there are any requirements to have identical hardware when it comes to a distributed deployment.

With that being said, it is probably a good idea to keep the Admin and Monitoring nodes on the same type of hardware specs.

Hi Abhishek,

There is no restriction on the model number but the versions running should be same on primary and secondary in the distributed deployment. Please look at the guidelines below:

You must first upgrade the secondary Administration node to Release 1.3. For example, if you have a deployment set up as shown in the following figure, with one primary Administration node (node A), one secondary Administration node (node B), one Inline Posture node (IPN) (node C), and four Policy Service nodes (PSNs) (node D, node E, node F, and node G), one primary Monitoring node ( node H), and one secondary Monitoring node (node I), you can proceed with the following upgrade procedure.
