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

...

Info

Note: 
In the case of Free Radius, SNTP, MRTG, and CACTI  should normally be installed before the migration (see the Dialogic IMG 1010 and 1004 documentation for more information).


Back out/Revert

For any reason, the GCEMS migration may be reverted to its pre-migration state, using the following steps: 

1.Close Clientview and Stop GCEMS by clicking on the desktop icon on both the Primary and Secondary GCEMS servers
2. Install the GCEMS/Clientview software on the Primary servers according to Dialogic IMG documentation for a standalone GCEMS setup, which is the default install. 
3. Start GCEMS on the Standalone server by clicking on the Start GCEMS desktop icon and select "2" to not load new config.
4. Launch Clientview by clicking on the Clientview desktop icon
6. Query All Tags by clicking on the Query All Tags tab.
