When switching from the COMmander/COMpact series to a new COMtrexx series PBX, you can use the COMtrexx migration tool to convert the configuration data, allowing you to easily transfer a large portion of the data.

Existing systems with analogue telephones can be migrated to a COMtrexx system by using analogue terminal adapters (ATA) or existing PBXs as a/b gateways.
