Yeah the hardest part is going around and updating your address with sites you use.
Every time I've done it, I've also put an auto forward on my old address, and a label or other alert for anything that comes through from the old so I can go update it or block that address from auto forwarding.
Word of warning, loads of those are full of hidden malware that will attempt to infect the other devices on your network. Probably best to make your own every time.
