You'll be following quite a chain of people who have migrated here if you do come. I moved over on Friday, and would thoroughly recommend it. Just be prepared for a culture shock, people answer phones, reply to emails and even phone you to check that all is well.
As to the router, you'll need to enter your new login details, but that's about it. There's also a backup 0845 number dial-up, so make sure you ask for that.
