I did this a while ago for my own and my wife's email and ten years ago I changed from .nl to .com for the domainname which is effectively the same thing :-) For both it's forward and forget, I changed some services to reflect the mail change, most I didn't bother. After 5 maybe 6 years no e-mail came through the old address anymore. So if you have the time and the couple of $$ to keep it up it's a minor issue, it's self cleaning to a large extent.
