I am stuck. I purchased a new domain and want to set up a custom email with Zoho. Problem is, my paid subscription only allows for one user, and I have everything attached to my old domain which I used with my free Zoho plan.

Since I am the only user, I don't want to buy another license.  

After I set up all my stuff at the new domain, I'm going to cancel the old one. How do I proceed?

Thanks
