One of life's only constants.
Correct.
I'm actually thinking (from what little I've heard and what I understand of this particular process) that is should go pretty smoothly. They're just upgrading to what we have here, although probably a version later (4.0.8 instead of 4.0.7) than what I'm currently running. 4.1 just came out this week and I'll probably install it in a week or so but it just has a bunch of bug fuxes...
