I think this would be the better method in this case.
Mails are stored in /var/lib/nethserver/vmail/
. You may use rsync to migrate files from one VPS to another.
Another method would be to transfer mails with a mail client like thunderbird or a mail sync tool like imapsync or dsync.
yum -y install imapsync
imapsync --host1 providerimapserver --port1 993 --user1 name@provider.at --password1 PASSWORD1 --ssl1 --host2 localhost --port1 993 --user2 name@domain.local --password2 PASWORD2 --ssl2
