Yes, ID sequencing needs to be pre-planned for data from multiple machines to coexist happily on a single target system. The Entity Engine can put a prefix on all sequenced IDs, configured on the delegator def in entityengine.xml. Of course, it depends on what the systems are for and the data that will be generated and tracked on each one. Usually just a few entities are moved over between the systems, and that should generally be as limited as possible.

Whatever the case, coordinating data between multiple systems is complex and what is being done should be well understood. It's not feasible to cover the potential problems and recommended solutions here, and of course those will change a lot depending on the circumstance.
