Cisco ISE 3.3 P2 stable to Upgrade from 3.2?

[md-shahnawaz]

Hello Team,

Need assistance from ISE engineer who already running ISE deployment on 3.3 version.

currently we are on 3.2 with latest patch, planning to upgrade to 3.3 with patch 2 only because 3.3 allow multiple integration features, before going to 3.3 wanted to hear from community stability of 3.3 version with end user machines, any service impact, any issue which we need to be alert before going to 3.3 version.

all your inputs are highly appreciated

I have been running ISE 3.3p2 for a few weeks now and I have not noticed any issues. I have upgraded two separate deployments, each from 3.2p5 to 3.3, using the GUI Split Mode upgrade. No issues with the upgrade either. It's really good now.

Every environment is different, and I will add that the environments I upgraded are not legacy ISE deployments that have been updated from 1.x, to 2.x, etc.  They are relatively fresh builds.  In my experience, upgrades can fail due to a long history of upgrading the same config.
