Migrating to IOS XR 64-bit OS

This document provides the procedure to migrate from Cisco IOS XR to Cisco IOS XR 64-bit operating system (OS) on the ASR9000 series routers.

Why Migrate to IOS XR 64-Bit OS?

IOS XR 64-bit operating system (OS) is the next-generation IOS XR OS that runs on virtualized environment with underlying 64-bit Linux kernel. Also, the key capabilities of IOS XR 64-Bit OS include:

  • Telemetry—push toward smarter visibility of the network by streaming data to a configured receiver for analysis and troubleshooting purposes.

  • Application Hosting—leverage hosting of third-party applications in a container environment.

  • Data Models—automate configurations that belong to multiple routers across the network.

  • Flexible Packaging—easy routine upgrades and maintenance with modularized Redhat Packet Manager (RPM) packages.

Migration Methods

Migration from IOS XR to IOS XR 64-bit OS can be carried out in different methods using:

  • Cisco Software Manager (CSM): Use this method to convert configuration, and schedule migration using CSM application.

  • Manual method: Use this method to manually prepare the system, use a script to migrate, and verify that the migration was successful.

After migration, setup the system and install packages. For more information, see System Setup and Software Installation Guide for Cisco ASR 9000 Series Routers.
