# This mimics the scenario where a single server has been used until now (no
# syncprov either, so no contextCSN) and we convert it to a delta-MMR setup:
# 1. stop the server (note that there is likely no contextCSN in the DB at this point)
# 2. configure all servers to delta-replicate from each other and start them up
# - empty servers will start with a refresh of the main DB
# - when the refresh is successful they should change over to replicating the log
# 3. keep making changes on all servers to see things still work
