Excellent. Thank you. Points awarded. My bigger issue, which I failed to disclose, is that I'm trying to migrate to a new host and not disrupt anything. Part of this was to change the architecture of the configuration store to redundant network storage (my question above).
After talking with Esri support, they said that there's no bulletproof way right now to move an ArcGIS Server site to a new host-- they might be working on a migration tool in 10.5, but that's a few months out I guess.
