Backup the existing system configuration before upgrading. Depending on the version software, the backup procedure varies. See below.
If upgrading from system software version 10.5.x, the configuration portion can be automatically backed up using the IMG 1010 - Collect Log File Button. Use this object to backup the /opt/dialogic/common/config folder. Once the config directory is backed up, manually create a backup of the license directory. From here the Installation of the system software files can be achieved. Move to the Installation section below after the backups are complete.
If upgrading from software 10.3.x the backing up of files will need to be achieved manually. The next few steps described how to back up files manually. Once all files are backed up manually, proceed to the Installation section below.
In ClientView, select File --> Save Configuration File. This will save the .csa file located in the /opt/dialogic/common/config directory.
Create a copy of the current configuration file by renaming the present configuration file to a new configuration file name. Follow steps in the table below to rename the configuration.

For a more in depth procedure on backing up the GCEMS server manually refer to the following tech note: How to correctly backup GCEMS files when upgrading IMG software versions |
Upgrading software from 10.5.0 to 10.5.1+ will create a local backup by automatically renaming the entire /opt/cantata directory to /opt/cantata_<timestamp>, and create a new /opt/dialogic directory. However, it is still recommended to perform a backup of all the files explained above before attempting the upgrade.

If using an SD Card to load system software, appropriate files must be transferred to the card. Files can be transferred to the SD card in one of two ways:
If IMG is using 10.5.0 or newer software, access to the SD card can be enabled in ClientView and the software can be transferred to and from the SD card using the ftp utility. Refer to the IMG 1010 - SD Card Remote Provisioning or IMG 1004 - SD Card Remote Provisioning topics for ore information on remote access to the SD card.
The second way is to use an SD Card Reader and copy the files through use of the reader. Refer to the IMG 1010 - Downloading System Software from SD Card or IMG 1004 - Downloading System Software from SD Card topics for more information on loading software using an SD card.
...
Follow the prompts. Refer to the IMG 1010 - Starting GateControl EMS topic which describes the installation process. The IMG_10.5.x.xxx.bin will be installed in the /opt/dialogic/installs/IMG_10.5.x.xxx directory. Once completed, you will be prompted to log out and then log back in. Do not log out yet, you will be prompted to log out later in installation process.

If installing the IMG software from an SD card, insert the card into the SD slot on the IMG. See IMG 1010 - Downloading System Software from SD Card.
If a new license has been received, copy it to the stand alone GCEMS server or to both the primary and secondary GCEMS servers in the /opt/dialogic/common/license directory.
Restart GCEMS
See IMG 1010 - Starting GateControl EMS for a single GCEMS.
For a redundant GCEMS system only start the primary GCEMS now.
For multi-node SS7 systems see IMG 1010 - Graceful Upgrade of Node to upgrade 1 IMG at a time.
If during starting of the GCEMS services you are being asked if you want to start a new configuration or start with existing configuration
Select start with existing configuration, wait for GCEMS services to start
Start ClientView. Refer to the IMG 1010 - Starting ClientView - Overview topic
Manually restart each IMG (select the Physical IMG object and then click the Clear Software button) when it is convenient to restart each IMG. The restart is required for the IMG to load the new firmware.
If you do not get the question when you start GCEMS services
Wait for GCEMS services to start
Restart ClientView. Refer to the IMG 1010 - Starting ClientView - Overview topic.
Load the desired configuration file. Click the load button to open and commit the configuration file (.csa).
At this point all IMG's will reboot.
