Well, I guess we don't have a lot of choice, really. This seems like the right way to go even if we take a performance hit. We'll only know the true performance hit once the move is made. 

In the event that the hit is so great that some functionality is effectively lost, can we still look into a plan b? (even if that means going down for a much longer period).

My plan is to put a down for maintenance message on the website. We don't want anyone submitting while we are doing a restore. Alternatively, if you have a way of disabling submissions, we do not need to disable the website.

I don't think we have an easy toggle for turning off submissions -- other than temporarily commenting out the login.jsp code. Do the developers see that as an adequate measure? 

Any night next week would be fine with me.
