It would be convenient if `fdbdr switch` ensured that each cluster had a `dr_agent` pointing to the other cluster before locking the new destination cluster. When I was experimenting with it, I incorrectly assumed that the `dr_agent` on the original source cluster would be enough. I was confused when the `fdbdr switch` command hung and both clusters were locked.
