+# 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
