I recently bought a house, and had all the joy that entails. I had my support people handling most of the frontline business / client requests, I checked in with the server maintenance people twice a day after giving them my new contact information, and other than that, I just took some downtime.
For your emigration, you might look into hiring some of the per-incident support companies out there. They will handle your support queues, and only charge you for the number of tickets actually handled. (This assumes you don't have anyone else working with you, not even part-time support personnel.) Check back in with any "temporary" folks (such as the third-party support providers) regularly, though - just to make sure that you can adjust to any Situations that may develop. Your check-ins may amount to nothing more than looking at your email queue, saying, "Nothing that can't wait another week", and shutting back down. But that gives you the hands-off time without getting you entirely out of the loop.
Good luck with the emigration!! Here's hoping that the Moving Gremlins demand a very small sacrifice (say, an extremely worn paperback and a few pairs of socks. Possibly that one grotty coffee mug you've managed to hang on to.)
