I continually refer to this short but informative article, thanks Shinji. Surprising how vague the internet can be on this issue.

Comment on Rolling mongrel restarts by Dustin Anderson

this isn’t a fully baked solution, but I’m thinking that if you have a master-master database setup, you could start by taking one of the databases offline, run migrations on it, and then start taking mongrels offline and restarting them in a new “pool”. You’d have to programmatically make it so the “new pool” of mongrels (already restarted) were waiting to serve requests, and were already hooked up to the migrated database.

You’d have to wait until requests dropped and then at some point you’d hold requests (it would have to be short enough so they wouldn’t timeout) and then as soon as all the old requests were processed on the old pool, you could start handling the requests from the new pool.

You could then merge the changes that the newly migrated database hasn’t seen from the old database. I dunno… seems sketchy. You’d have to make sure all those requests don’t conflict with anything. I think you’re screwed dude.
