installed).

To perform a manual upgrade:

1. In-place upgrade: Install the latest version over your existing version of ESET Mail Security by following the steps

in the Installation chapter. All existing settings (including antispam settings) will automatically be imported

into the newer version during installation.

2. Clean installation:

a) Export your configuration/settings to an xml file using the Import and export settings feature.

b) Open this xml file in a dedicated xml editor or a text editor that support xml (e.g. WordPad, Nodepad++,

etc.), then change the third line SECTION ID number to "1000404" so that it looks like this:

c) Download the EMSX AntispamSettingsExport tool from this Knowledgebase article. Save

EMSX_AntispamSettingsExport.exe to the Exchange Server you are upgrading to the latest version of ESET Mail

Security.

d) Run the EMSX_AntispamSettingsExport.exe tool. The tool will create a cfg.xml file containing the antispam

settings from your existing installation of ESET Mail Security.

e) Download the msi installer file for the latest version of ESET Mail Security.

f) Copy the cfg.xml file created by the EMSX AntispamSettingsExport tool to the same location where you

saved the ESET Mail Security msi installer file (e.g. emsx_nt64_ENU.msi).

g) Uninstall your existing version of ESET Mail Security.

h) Run the msi installer for ESET Mail Security 4.5. Antispam settings exported to cfg.xml will automatically be

imported to the new version.

i) Once the installation is complete, import the configuration/settings from the xml file that you saved and

modified in steps a) and b) using the Import and export settings feature and an xml editor so that you

can use your previous configuration settings in the new version of ESET Mail Security.

After performing the steps above, you will have the new version of ESET Mail Security installed on your system with

your previous custom configuration.

For more details regarding upgrade process see this Knowledgebase article.

NOTE: Both manual upgrade processes (in-place and clean installation) apply to the upgrade from ESET Mail

Security version 4.2 or 4.3 to ESET Mail Security version 4.5 only.

2.5 Exchange Server Roles - Edge vs Hub

By default, an Edge Transport server has its antispam features enabled and a Hub Transport server has its antispam

features disabled. In an Exchange organization with Edge Transport server, this is the desired configuration. We

recommend that you have the Edge Transport server running ESET Mail Security antispam configured to filter

messages before they are routed into the Exchange organization.

The Edge role is the preferred location for antispam scanning because it allows ESET Mail Security to reject spam

early in the process without putting an unnecessary load on network layers. Using this configuration, incoming

messages are filtered by ESET Mail Security on the Edge Transport server, so they can safely be moved to the Hub

Transport server without the need for further filtering.

If your organization does not use an Edge Transport server and has only a Hub Transport server, we recommend

that you enable antispam features on the Hub Transport server that receives inbound messages from the Internet

via SMTP.
