Export one mailbox and change ip/certs


I have one instance of mailinabox in a location, i neet to export one account and one domain name to another location B with different ip address.

I dont want to use duplicity and copy all accounts, i just need to copy one domain and account.

And second questions, how i can reconfigure new address to letsencrypt cert?

Mail can be copied manually from “/home/user-data/mail” and you just need to setup the new server with the domain and change MX records to point to the new server.
