Building a Quarterly Pilot/Prod Patching Process

Hello,

I work for an MSP and we are trying to build a quarterly prod patching process that includes a pilot group scenario for a particular client and future clients. We currently use Kaseya(we are looking at moving off Kaseya for patching with a possible move to ManageEngine) and the communication from them is that based on how Microsoft handles superseding of Monthly CU/Rollups the Pilot and Prod patching would need to occur in between the releases of Monthly CU/Rollups to avoid superseding making a patch inapplicable. We are looking for suggestions/recommendations/work arounds/lessons learned on how to handle that process and fit within Microsoft's superseding of Monthly CU/Rollups. The particular client would like a 4 week gap between the Pilot group getting the monthly CU/Rollups and rollout to Production which is split into 2 weeks.
