cPanel to mailcow migration guide

These are the steps I followed to migrate my emails from cPanel to mailcow:

1. Create & run a shell script
   Gist

   get all emails and their password hashes from a cPanel server

   get all emails and their password hashes from a cPanel server - get_cpanel_emails.sh

   
   to get all email accounts and their hashed passwords on the cPanel server
2. Copy the values over to a spreadsheet and format it as follows (without the headers):

4. Export it as comma separated csv and use mailcowtools
   GitHub

   mailcowtools/addMailboxes/addMailboxes.js at master · rallisf1/mailcowtools

   Simple tools that use the mailcow API. Contribute to rallisf1/mailcowtools development by creating an account on GitHub.

   
   to import it via the API. Note that I have updated it to autocreate the domains and support domain plans (manually because mc API doesn’t provide a templates endpoint).
5. Use imap sync if you know the passwords or rsync/scp to copy the email data over from cpanel to mailcow. I used scp.

If you use scp/rsync like I did you need 2 more steps:

1. Run the encrypt commands from the documentation
   docs.mailcow.email

   Mail crypt - mailcow: dockerized documentation

   None

   
2. run docker compose exec dovecot-mailcow doveadm quota recalc -A
