Updating the Management Console component
On the computer with only the Management Console installed, the Installation Wizard updates only the Management Console. The Installation Wizard installs no Security Server modules on this computer.
Application settings do not change after Management Console is updated. The settings of the Microsoft Management Console interface take their default values.
Updating the Security Server component
On the computer with Security Server installed, the Installation Wizard updates all installed Security Server modules.
During an update, the Installation Wizard transfers the values of settings and data from the previous version of the application to the new version as follows:
If you do not upgrade the application but remove it and then install 9.0 Maintenance Release 4 instead, the previous version of the Backup and statistics database will not be upgraded to 9.0 Maintenance Release 4, which will make it inoperable in the application.
If you are using different white lists / black lists of Anti-Spam addresses for different servers of the DAG group (applicable for application versions 9.0 – 9.2), you are recommended to export the lists of Anti-Spam addresses from all servers of the group to files and import the saved lists to the first server of the group prior to updating the application. During the update, this list will be applied to all servers of the group. You can also synchronize the white lists / black lists of Anti-Spam addresses in the PowerShell environment for all servers of the DAG group with the white lists / black lists of the first server of the DAG group.
