Because the SmarterMail download contains all of the installation files needed
for any licensing level or edition, upgrading editions or levels is relatively easy.
With a valid license key, companies can easily upgrade to the professional or enterprise
editions or increase the number of mailboxes available in SmarterMail. For more
information, see the Activating SmarterMail
section of the online help. For step-by-step instructions, please refer to the KB
article How To - Upgrade SmarterMail Levels and Editions.
The steps for upgrading to SmarterMail from an older version of the application
vary depending on which version you are currently using. For more information, please
refer to the KB article How To - Upgrade SmarterMail.
