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.

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.
