Failed migration from Dovecot server

[vooxo]

Hello,

Hello, I'm trying to migrate from an older cPanel server to the new mailcow-dockerized - but can't make it to work.

I've done the following:

1. copied emails from the old server; directory structure is as described here: https://www.thecpaneladmin.com/understanding-courier-imap-and-maildir/
2. put files to:
3. /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/
   so that the structure is /var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/example.com/username
4. chown'd everything to 5000:5000
5. ran docker-compose exec dovecot-mailcow doveadm quota recalc -A
6. restarted docker

Nothing works...

Question 1:
How do I actually associate the password data from old server's /home/username/etc/shadow ?

Question 2:
Where do I get private and public*.pem keys which are required in the encrypt script ?

What am I missing?

Thank you!

I'm afraid nothing works is too generic. You have to be more specific.

I'm just migrating old server and it works. But I've created domains in Mailcow, I've added users through API and I've only migrated e-mails from Cur directories.

Q1: You have to update passwords in database adding hash type in the beginning. Like: {PLAIN-MD5}058ef3a0d1812383bdad58552be0eb44

Q2: You don't have to encrypt old e-mails - they are visible without it.

I've added users through API

Using what passwords?

So, how have you actually transferred passwords from the /home/username/etc/shadow file to the new server and associated them with users?

Just the same generic password for everyone - it's overwritten later.

I had my passwords in the old mail server database already, but I think it doesn't really matter - you can generate update script from a file.

Thank you for these tips, I'll try it out.
