Before upgrading, you must not forget to read the errata file
Before any upgrade attempt it is highly recommended to make a backup of the following directories:
/var/www/virtual
/var/mail/virtual
These directories hold the data of your customers and it is really important to backup them for an easy recovering in case something goes wrong during upgrade.
