We already updated this week and it works without any issues so far.

Nothing besides the steps in this guide were done: Upgrading the Jamf AD CS Connector - Technical Paper: Integrating with Active Directory Certificate Services (AD CS) Using Jamf Pro | Jamf

easiest. update. ever. 

Does this upgrade require any re-configuration apart from whats included on the guide ?  and also does the new version works with previous versions of JAMF Pro ? I have not upgraded to latest jamf pro version as yet.

not sure on the previous versions but im at 11.7.1 and simply following the directions provided updated everything, no work in jamf pro needed
