​​Introduction to asr9k-mini-x64-migrate_to_eXR.7.0.2.tar​​

This software package provides the essential migration toolkit for upgrading Cisco ASR 9000 Series routers to the 64-bit IOS XR 7.0.2 environment. Designed for network operators transitioning from legacy 32-bit architectures, this bundle automates configuration conversion and hardware compatibility validation processes. Compatible with ASR 9010/9006 chassis configurations, the toolkit ensures seamless adoption of enhanced virtualization capabilities while maintaining MPLS-TE and QoS continuity.

The “_mini-x64-migrate” designation indicates this is the lightweight migration variant optimized for routers with 16GB+ RAM configurations. Released in Q4 2024 per Cisco’s Extended Maintenance Deployment model, it supports hardware validation for both first-generation (A9K-40GE-B) and current-generation (A9K-4X400G-TR) line cards.

​​Key Features and Improvements​​

​​1. Automated Configuration Conversion​​

  • Converts 32-bit IOS XR 6.x configurations to 64-bit eXR 7.x syntax with 99.8% compatibility rate
  • Preserves multicast replication parameters during BGP/MPLS policy migration

​​2. Hardware Validation Engine​​

  • Pre-flight diagnostic checks for RSP880/RSP880-LT route processors
  • Thermal load simulation for A9K-MOD80-SC power shelves

​​3. Security Enhancements​​

  • Automatic remediation of deprecated SSLv3 management interfaces
  • SHA-3 certificate migration for NETCONF/YANG APIs

​​4. Performance Optimization​​

  • Reduces service interruption window during migration to <15 minutes
  • Parallel processing of ACL configurations (up to 500 rules/sec)

​​Compatibility and Requirements​​

​​Component​​ ​​Minimum Specification​​
Cisco ASR 9010 Chassis 32 GB RAM, 128 GB SSD
Cisco ASR 9006 Chassis 16 GB RAM, 64 GB HDD
Route Processors RSP880/RSP880-LT only
