If all goes well it should be back up in a matter of a few minutes.
Or cry later
If the update goes to heck in a hand basket (worst case scenario), then the site will be down for the weekend. But I doubt it'll come to that.
I'm taking steps to make sure the site is fully backed up and ready to bring the site back in case I get in over my head.

Rest assured, I kind of know what I'm doing.
