My account is attached to an old business email, can't access my trello

[Jade Dupre]

I opened Trello under a business that I owned, with a gmail address that I no longer pay for. Now I can't login to Trello on my computer because I can't access the gmail account. The app still works for me and I've built out boards that I don't want to lose. How can I transfer the boards to a new account or how can I update my email address under my trello account
