SD-WAN Migration & Overlay Modernization Services

Build a Smarter, More Agile WAN

Legacy MPLS networks were never designed for the cloud-first, hybrid-work world. The cost is high. The flexibility is low. And adding new sites or optimizing for cloud traffic is painfully slow.

Modern SD-WAN platforms change that, but only when designed and deployed right. Without a plan, SD-WAN can quickly create more problems than it solves:

  • Performance degradation from poor path selection
  • Insecure internet breakouts
  • Misaligned policies across sites
  • End-user frustration due to inconsistent app experiences

That’s why we take a structured, phased approach. Intelligent Visibility designs and executes SD-WAN migrations with clarity, precision, and business alignment at every step.


Advanced Network Infrastructure and Design Services

The Risks of a “Quick Cut” to SD-WAN

  • Incomplete Visibility: Without baselining app traffic, performance may suffer post-migration.
  • One-Size-Fits-All Design: Every site has unique requirements- generic overlays won’t cut it.
  • Security Gaps: Local internet access without integrated SASE or policy controls is a risk.
  • No Back-out Plan: A big-bang cutover can lead to business disruption and reputational damage.

 

Our SD-WAN Migration & Modernization Services

We provide a full suite of services to ensure your transition to SD-WAN is seamless, secure, and aligned with your business outcomes.

SD-WAN Readiness & Performance Baselining

Before any changes, we capture a full view of your WAN’s current state:

  • Application traffic flows
  • Site-to-site routing patterns
  • Latency, jitter, and utilization benchmarks

This ensures your new SD-WAN overlay is designed to meet or exceed your current SLAs—and that you can measure success post-migration.

SD-WAN Overlay Design

We architect a resilient and application-aware overlay using:

  • Hub-and-spoke, full mesh, or hybrid topologies
  • Business-aligned routing policies and SLAs
  • Quality of Service (QoS) prioritization for voice, video, and real-time apps
  • Redundant path strategies with automated failover

Our designs are built for performance, uptime, and scalability- not just connectivity.

Phased Migration Planning

We create a step-by-step migration roadmap that balances speed with safety:

  • Site-by-site staged cutovers
  • Parallel operations (MPLS + SD-WAN) for testing and validation
  • Hybrid options for environments that require both for compliance or operational reasons

This reduces risk and ensures zero surprises during rollout.

Pilot Program & Proof-of-Concept

We always recommend starting small—with 1–3 sites—to:

  • Validate the design and overlay behavior
  • Measure real-world application performance
  • Train your team on SD-WAN operation

Lessons learned here drive smoother full-scale deployment.

Secure Local Internet Breakout & SASE Integration

To unlock the full value of SD-WAN, we implement secure direct-to-internet access at the branch:

  • Intelligent breakout policies based on app ID, SLA, or user role
  • Integrated security controls or policy enforcement with cloud firewalls or SASE platforms
  • Consistent policy and identity enforcement from core to cloud edge

This supports modern work without sacrificing control.

FAQs: SD-WAN Migration

Can we run SD-WAN and MPLS in parallel during the migration?

Yes. Most clients use a hybrid approach for a period of time. We design migration paths that support full coexistence until you’re ready to cut over.

Do we need to replace all our routers?

Not necessarily. Many SD-WAN platforms can run on existing hardware or as virtual appliances. We assess your environment and make cost-effective recommendations.

How long does a full SD-WAN migration take?

Timelines vary based on number of sites and complexity. Many clients start seeing value within 30–60 days with pilot and phased cutovers.

Can we integrate our SD-WAN with cloud security platforms (SASE)?

Yes. We routinely integrate SD-WAN deployments with SASE services like Zscaler, Prisma Access, and Cisco Umbrella to unify networking and security.

Do you support co-managed operations post-deployment?

Absolutely. Through our Aegis platform, we provide proactive monitoring, policy management, change assistance, and lifecycle support in a shared-operations model.

Experience the Difference: Proven Expertise, Tangible Results?
