Hi Alexis, depends on your full setup and what's the relation between the 2 (DMP-DMA).
DMP's are typically installed at remote sites. Additionally, in many cases it's also preferred to have a main DMA to act as a central point to monitor & control your full network. This can be accomplished by replicating the elements running on the DMP towards the main DMA. In this use case it's important that the DMPs are running the same DataMiner version as the main DMA.
