Nope, I'm one version back on all -- 11.5.2 / 7.3.1
The only issue I've ever had in the past is with the additional poller engines and licensing of FOE
Thanks it's good to know that at least those are working for someone. I got behind on releases so I'm looking to move my NPM 10.6 / NCM 7.1.1 into the present.
I actually only keep FOE on the NPM and SQL servers (and I hate it on SQL). I dropped the poller FOE a long time ago. Just didn't see worth it, I just added alarming if nodes are not polling.
