How will you switch back to the new server once it's ready without losing database records?

I guess the same way we switched to this one?

I wrote more about data loss at https://news.ycombinator.com/item?id=32030407 in case that's of interest.

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.

Ah, 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.

Not a problem in a thread about replicas and redundancy :)

So there's this great joke about cache coherency.

I'm sure you'll get it, eventually.
