Introduction
Dialogic IMG 1010 Integrated Media Server documentation describes how to install two redundant Dialogic Gate Control Element Management (GCEMS) servers in a new installation, but does not describe how to migrate to a redundant configuration after you have already established a single server (non-redundant) configuration.
This article describes how to implement redundant GCEMS servers starting with a single stand-alone (non-redundant) server, by adding a single new server.
If you wish to install two new servers please see the following article: Migrating from an existing GCEMS to two new redundant servers

4. Copy the IMG licenses from /opt/dialogic/common/license/ directory over from the current standalone server to the new secondary GCEMS server in the same /opt/dialogic/common/license/ location.
5. Close Clientview and GCEMS on the standalone server by clicking on the Stop GCEMS desktop icon
6. Install the GCEMS software on the 2 servers according to Dialogic IMG documentation for IMG 1010 - GCEMS_Redundancy_Configuration
7. Start GCEMS on the Primary GCEMS by clicking on the StartGCEMS icon on the desktop and when prompted enter "2" to not load new config. When selecting this option the Primary GCEMS will load the current system.cfg and will not result in any downtime.
8. Start GCEMS on the Secondary GCEMS and when prompted enter "2" to not load new config. When selecting this option the Primary GCEMS will ftp the current system.cfg and system_datamodel.xml to the Secondary GCEMS.
9. Clientview can be ran on each of the GCEMS servers, however it is normal to start Clientview first on the Primary as it will have the configuration privileges. When launching Clientview you will need to either enter the IP or hostname of the Primary and Secondary GCEMS servers.
