Cisco IOS to Juniper JunOS Router Migration

Migrating from Cisco IOS/IOS-XE to Juniper JunOS? NetConverter's comprehensive multi-step pipeline automates the conversion of routing protocols, interfaces, ACLs, and QoS policies with 95%+ accuracy and confidence scoring.

The Router Migration Challenge

Syntax Differences

Cisco's CLI-based hierarchical config vs JunOS set commands require complete restructuring of every configuration element.

Routing Protocol Mapping

BGP, OSPF, and EIGRP configurations have different syntax, knobs, and policy frameworks between vendors.

ACL Translation

Cisco ACLs must be converted to Juniper firewall filters with different match conditions and action syntax.

How NetConverter Solves It

Intelligent Syntax Translation

Our translation pipeline understands both Cisco and Juniper semantics, translating config intent rather than just syntax.

Protocol-Aware Mapping

BGP policies, OSPF areas, and route-maps are translated with full understanding of vendor-specific features.

Complete ACL Conversion

Access lists become firewall filters with proper term structures, from/then clauses, and action mappings.

4-Tier Validation System

Every translation undergoes comprehensive validation: syntax correctness, semantic accuracy, vendor best practices compliance, and AI-assisted review.

Confidence Scoring

Each conversion includes a confidence score indicating translation quality, helping you prioritize review efforts and ensuring production readiness.
