TFL server upgrade coming up tomorrow (maybe)

Heads up that an upgrade to the server TFL runs on is coming up soon. It's actually a migration to a new machine, not an in place upgrade. That's a safer approach because if anything goes wrong I can bail out and leave the site and server as they are right now.

I'm hoping to take care of it tomorrow late afternoon Pacific time but it might not happen until later in the week. I'll post another announcement an hour or so before I start.

I've run the test migration twice already and the migrations have gone very well. Expect about an hour of read-only access to the site while I back up and copy everything from the old box to the new. 

Post-migration, hopefully the site just looks and acts like it does now. This isn't a software upgrade, though that is hopefully coming before too long too.
