I started using it for business many years ago and there are thousands of people that have my AOL email address. It would be too much trouble to change-over now and risk losing a potential client.

Just email everyone on that list your mew email address. It’s not that hard.
We changed from AOL to gmail at work. It was an very easy transition.
Just send a mass email out to ALL contacts stating your new email address.
That’s what we did and it was a very smooth transaction.
