Upgrading to a newer version

New versions of ESET Mail Security are issued to provide improvements or fix issues that cannot be resolved by automatic updates to program modules. It is possible to perform an upgrade from older versions of ESET Mail Security (4.5 and earlier) even though it is an upgrade to a different architecture.

Manually - by downloading and installing a more recent version over your existing version. Simply run the installer and perform an installation as usual, ESET Mail Security will transfer your existing configuration automatically. We recommend this procedure if you have a single server running ESET Mail Security. Applicable for upgrades from any old version to 6.x.
Remotely - in a large network environment using ESET Remote Administrator. This method is useful if you have multiple servers running ESET Mail Security. Applicable for upgrades from version 4.x to 6.x.
ESET Cluster wizard - can be used as an upgrade method. It is very straightforward procedure that lets you upgrade old versions of ESET Mail Security running on your servers. Also, once the upgrade is completed, you can keep using ESET Cluster and take advantage of its features. We recommend this method for 2 or more servers with ESET Mail Security. Applicable for upgrades from version 4.x to 6.x.

There are some exceptions during upgrade, not all of your settings will be preserved, in particular Rules. This is due to the Rules functionality being completely redesigned in ESET Mail Security 6. Rules in previous versions of ESET Mail Security are not compatible with Rules in ESET Mail Security version 6. We recommend you to configure Rules manually by defining email filtering conditions and actions to take with filtered emails. New Rules gives you greater flexibility and even more possibilities compared to Rules in previous version of ESET Mail Security.

 

Following is a list of settings that are preserved from previous versions of ESET Mail Security:

General ESET Mail Security configuration.
Antispam protection settings:
All settings that are identical in previous versions, any new settings will use defaults.
Whitelists and blacklists.
