Which option is better for 2.0 to 2.2 upgrade

Hello ,

Hope all are doing good.This is my first post in communities

I am planning to upgrade ISE in our production environment which is running on ISE 2.0 with patch 5 to ISE 2.2

I get mixed opinion from different engineers about GUI and CLI upgrade and am bit confused to proceed with ..

Option 1 (Via GUI)

install ISE 2.2 and install Patch 1 at the same time

Option 2 (Via CLI)

- De register Secondary node from a deployment and Upgrade it via the CLI and check that it is perfectly fine and works.

- De-register 1 PSN from deployment and ideally re-install a 2.2 fresh install on it

- Add the fresh installed 2.2 node to an upgraded 2.2 secondary admin to a new deployment.

- Proceed with other nodes and added to the deployment with ISE 2.2

So This way you will have a 1 node upgraded and it will retain all the configuration and then when you add a new nodes to this one they will replicate a configuration from it.

Both option 1 and option 2 are heard from TAC engineers

Our system team is upgrading to Active Directory 2016 and ISE 2.2 only support AD2016. So its mandatory for me to upgrade the ISE to 2.2 version

I am having 4 nodes in our environment

- Primary admin / Primary Monitoring

- Secondary admin / Secondary Monitoring

- PSN 1

- PSN 2

If anyone  successfully upgraded to ISE  2.2 please let me know the procedure followed for that and also mention if there is any major issues after the upgrade

Thanks a lot in advance

Re: Which option is better for 2.0 to 2.2 upgrade

Hi Shabeer,

i wouldn't suggest to use the GUI Upgrade function. A couple of colleagues tried in the past and it didn't worked very well.

I'm always using the good old cli upgrade method. Login to the vSphere Console of the VM's and start to upgrade like it's described in the cco documentation. Cisco Identity Services Engine Upgrade Guide, Release 2.2 - Upgrade a Cisco ISE Deployment from the CLI [Cisco Identit…

But do a Backup of your configuration and if you need it your Operational Data before. Depending of the Performance of you Hypervisors it's maybe an Option to do a clean install of the PSN's and calculate with a decent amount of time for the Upgrade. I saw upgrade times of 2 to 4h for pan/mnt nodes.

After the Upgrade check the Post-Upgrade Tasks
