CISCO ISE and DNAC integration

[lilimtzrmz]

I have a question regarding a new ISE deployment that will be integrated with DNAC. It's greenfield deployment for both ISE and DNAC. The recommended version for DNAC is 2.3.5.5, and after checking the compatibility table with ISE, version 3.2 p5 is recommended for the integration. However, the currently recommended version of ISE is 3.3.

If the appliance arrives with version 3.3, would we need to re-image it to 3.2? From my perspective, it would be best to stick with the Cisco-recommended version since it's supported for that DNAC version, but I want to avoid TAC saying downgrade since the compatibility matrix mark 3.2 is the recommended one.

ISE 3.3 patch 2 is current stable version, so stay with 3.3 and integrate with DNAC, don't downgrade to 3.2

additionally you can read 3.3 release notes and make sure there is not any open caveat which will effect your integration, I did not see anything significant. Also make sure your infrastructure is compatible
