Question Server restored but I have a newer mailnames folder

[NeoTrafy]

Server operating system version

Almalinux 9

Plesk version and microupdate number

Plesk 18.0.65

I restored my Plesk into a new server using an old backup dated on 4 november but I still have access to the old server with the mailnames intact which means I have mails up to 1st december.
If I copy the mailnames folder will it override those mails and keep working as expected? Or it will be duplicated because the backup change some kind of ids? And I had a little server working for the 5 days the server was out of service to give the clients a fresh mail, copy the folder will work or the best way is to download with thunderbird/outlook and setup the new one to upload those mails again.
Thanks in advance.

I think in this case, it is best to use the Plesk Migrator.

Migrating via the Plesk Interface

Log in to Plesk on the destination server as the Plesk administrator. Go to Server Management > Extensions > ...
