You switched to the new one while the old one was down... that's not the same as switching between two live systems. Though, perhaps, in this particular case, the procedure might be.
- dang 4y agoAh, I see. If we have to bring HN down for a few minutes, or (more likely) put it into readonly mode for a bit, we can do that–especially if it makes the process simpler and/or less risky.
