Just a note on the side here – element replication does not run via dataminer.services, it is peer to peer between two DMAs (typically each in another DMS – although it can be between any two DMAs). And as Miguel pointed out, both source and destination DMAs need to be the same version (although I believe that it doesn’t necessarily mean that it would not work if they are not), and both need the same driver (associated with the element that is being replicated).
