2.3 Upgrading to a newer version
Newer versions of ESET Mail Security are issued to bring improvements or fix issues that cannot be remedied by
automatic update of the program modules. Upgrade to a newer version can be accomplished in several ways:
1. Automatically by means of a program component update (PCU)
Since program component updates are distributed to all users and may have impact on certain system configurations,
they are issued after a long period of testing for seamless upgrade on all possible system configurations. If you need to
upgrade to a newer version instantly after it has been released, use either of the following methods.
2. Manually by downloading and installing a new version over the previous one
At the beginning of installation, you can choose to preserve current program settings by selecting the Use current
settings check box
3. Manually with automatic deployment in a network environment by means of ESET Remote Administrator
2.4 Installation in a clustered environment
A cluster is a group of servers (a server connected to a cluster is called a "node") that work together as a single server.
This type of environment provides high accessibility and reliability of available services. If one of the nodes in the
cluster fails or becomes inaccessible, its functioning is automatically covered by another node in the cluster. ESET Mail
Security fully supports Microsoft Exchange Servers connected in a cluster. In order for ESET Mail Security to function
properly, it is important that each node in a cluster contains the same configuration. This can be achieved by applying
a policy using ESET Remote Administrator (ERA). In the following chapters we will describe how to install and
configure ESET Mail Security on servers in a clustered environment using ERA.
Installation
This chapter explains the push installation method; however this is not the only way to install a product on the target
computer. For information on additional installation methods, refer to the ESET Remote Administrator User Guide.
1) Download the ESET Mail Security msi installation package from the ESET website to the computer where ERA is
installed. In ERA > Remote Install tab > Computers, right-click on any computer from the list and choose Manage
