Upgrading DGE Hardware

As the load on a DGE increases, it may be necessary to perform upgrades to the capacity of the hardware to increase the physical limits of the machine. If the upgrade involves addition of resources—memory, disk space, etc.—to the same machine, no special steps need to be performed. However, if the physical server is being upgraded for any reason, then the following steps need to be performed. Refer to the section on database backup/restoration for additional details.

Moving a DGE to a New Host

1. Install Traverse on the new host, making sure to use the same DGE name as the old one when asked during the install. Otherwise you will need to edit <TRAVERSE_HOME>/dge.xml and configure the DGE name there.
2. If the new host will have a different IP address, then you also need to log in to the Web Application as superuser, navigate to Superuser > DGE Management, and change the IP address of the relevant DGE.
3. Copy the following directories and files in their entirety from the old host to the new host:

database/
plugin/
etc/licenseKey.xml
etc/dge.xml
etc/emerald.xml

1. Restart the new DGE.
