Well inevitably this is gonna drop midway through October. If you check old stats, notice how activity is the same as September (or very close) for the first half of the month, then suddently goes down drastically for one or two week. If it remains extremly high I'll probably just do it during nights or early morning when not a lot of people are on. (such slower transition to the new server might cause some site features like downloads and attachments to be temporary disabled)
