If your having several instances load-balanced, you can easily update your site, one instance after another. No server runs mono-process. What do you think?



If it works like this, it's a great feature. But what's happening when in an update the database structures are changed?

There's no easy answer to your question. Although Opa raises warnings when it detects that the databases your accessing/trying to modify have changed, I guess you'd have to think of a migration process anyway.

What is your best practice so far? (and your expectations :p)
