MD-102 Old vs New Exam

MD-102 Endpoint Administrator replaces MD-100 + MD-101

As Microsoft has been moving away from on-prem tools like SCCM and Domain Controllers to cloud they introduced a new exam to reflect this change towards the cloud and tools like Intune, Entra, and Autopilot. And for the new Endpoint Manager that also meant a new certification to replace the old MD-100 Windows Client, and MD-101 Managing Modern Desktops.

As a budding Systems Administrator, MD-102 Endpoint Administrator is a good way of learning about modern Endpoint Management and protection, as well as document my knowledge. But how much of the old ways should I also learn?
