My email provider is terminating the existing email domain name, and replacing it with a new domain name. I want to retain all existing Thunderbird folders and emails for use with the new email. Example: username@q.com becomes username@myclk.com. (Yep, it's Centurylink.) Can I change my existing Thunderbird account name and email and retain all existing folders and emails in the account? Some server settings would also be changed. Or, do I need to set up a new account? Thanks
