2 Overview

Oracle Communications Diameter Signaling Router (DSR) creates a centralized core diameter signaling layer that relieves LTE, IMS, and 3G diameter endpoints of routing, traffic management, and load balancing tasks. DSR provides a single interconnect point to other networks.

This section provides information about DSR Migration from release 8.6.x BareMetal (BM) to 9.0.1 VM and later.

You can migrate DSR from release 8.6.x BM to 9.0.1 VM and later using following methods:

• Method 1: By reusing the existing hardware and IP addresses of NOAM, SOAM, IPFE, and DAMP. Using this method, you can shut down the DSR 8.6.x applications on BM and deploy them on VM using existing IP addresses.
• Method 2: By reusing the existing hardware and new IP addresses of NOAM, SOAM, IPFE, and DAMP. Using this method, you can shut down the DSR 8.6.x applications on BM and deploy them on VM using new IP addresses.
• Method 3: By using new hardware and the existing IP addresses of NOAM, SOAM, IPFE, and DAMP. Using this method, you can shut down the DSR 8.6.x applications on BM and deploy new NOAM, SOAM, IPFE, and DAMP, on VM using existing IP addresses.

Note:

From DSR 9.0.1 and later, there is no support for the BM environment. Therefore, to upgrade from DSR 8.6.x to DSR 9.0.1, you must perform the migration process outlined in this document.
