# This script converts the DB layout of the old mailserver guide (Ubuntu 14.04) [1]
# to the new one, introduced with Ubuntu Xenial (16.04) [2].
# Please note that the DB schema / tables for the new schema already need to exist.
# This script is just transferring / converting table _contents_.
#
# No not forget to provide your own database name and credentials in the 
# MySQL "connect" commands at the beginning of the script!
#
# Prerequisites:
#  apt install python3-pip
