5.4.2 Upgrade from earlier version
If you are currently using a previous version of GFI MailEssentials
(versions 9, 10, 11, 12 and 14), you can upgrade your current
installation while at the same time retain all your existing configuration
settings.
Important notes
 Upgrades cannot be undone i.e. you cannot downgrade to an
earlier version once you have installed the latest version.
 On upgrading an existing installation, licensing reverts to trial
version and a new fully purchased license key for the GFI
MailEssentials 2010 is required. For more information on new
license keys, refer to: http://customers.gfi.com.
 You cannot change the installation path during GFI MailEssentials
upgrades.
 When upgrading from GFI MailEssentials 9, the current Bayesian
weights file will be upgraded to the new format used in GFI
MailEssentials 10 or later. The new format is more compact and
uses less memory. NO DATA WILL BE LOST.
