SD-WAN Migration · Multi-Site
Senior-led SD-WAN migration and deployment for multi-site organizations replacing MPLS, consolidating ISPs, or upgrading from a generation-old SonicWall / Meraki edge. Built primarily on Fortinet SD-WAN (we’re a Fortinet Engage Advocate Partner) with documented site-by-site migration paths, parallel deployment options, and rollback plans. The kind of project that should not blow up your operations — and won’t.
Track Record
We only do networks. That is not a limitation — it is why the outcomes are different.
Years of network-only practice. Architecture, security, and operations — not IT generalism.
Sites delivered. Healthcare clinics, law offices, financial branches, multi-site operations.
Unplanned downtimes following network redesigns. Every implementation, with the precision it requires.
Senior engineer–led. No junior handoffs. No ticket queue. No escalation chain.
Career aggregate. The 20+ years and 300+ sites span the operator’s full network-only practice, including prior-employer engagements. Zero unplanned downtimes reflects post-redesign performance on engagements where the architecture standard described above was applied.
Why SD-WAN Projects Go Wrong
SD-WAN itself is mature. Fortinet, Cisco, VMware/Velocloud, Versa, Aruba — the platforms work. The failures we’ve seen reviewing client environments are migration failures: insufficient site assessment, missing rollback plans, poorly tuned SLA-based steering, ISP combinations that look right on paper but fail at the application layer. SD-WAN migrations that go badly are projects that didn’t document their assumptions.
Every site gets an actual assessment before cutover — current circuit, traffic patterns, application dependencies, identity-provider integration paths, on-site cabling realities. Generic SD-WAN vendor assessments miss the boring details that cause the actual outages on cutover day.
Every migration has a written plan: parallel deployment strategy, scheduled cutover windows per site, validation steps, rollback paths. We don’t cut over a site without a written rollback that’s been reviewed. Operations leaders sleep better knowing what happens if cutover-day finds the unexpected.
Multi-site SD-WAN migrations roll out site-by-site, not all-at-once. Pilot with one or two sites, validate the architecture in production, then deploy to the rest in waves. Each site cutover is its own contained project — if something goes wrong at site 5, sites 1–4 are still running fine on the new architecture.
We’re a Fortinet Engage Advocate Partner. We primarily migrate clients onto Fortinet SD-WAN because the SD-WAN, secure remote access, authentication, and Wi-Fi platform consolidation eliminates the stitched-together stacks most clients are coming from. Other SD-WAN platforms (Velocloud, Meraki SD-WAN, Versa) we can support but don’t recommend as new-build standards.
SD-WAN Migration Phases
Migrations break down into discrete phases, each with its own deliverables. Skipping any of them is how projects fail.
Per-site inventory of current circuits, traffic patterns, application dependencies, and identity-provider integration paths. Gap analysis between current state and target architecture. Output: site-by-site migration matrix with prioritization based on complexity and risk.
SD-WAN topology design (hub-and-spoke, full-mesh, or hybrid), application-steering policies, SLA-based path selection, ISP combinations, FortiManager orchestration scope. Reviewed with your team before any deployment. Documented decision rationale captured in writing.
One or two pilot sites cutover with full instrumentation: synthetic application monitoring, ISP path quality measurements, user-experience tracking. Run in parallel with old architecture for 1–2 weeks before declaring pilot success. Adjust architecture based on real production behavior.
Remaining sites cut over in waves, typically 3–5 sites per wave with 1–2 weeks between waves. Each wave validated against the same metrics as pilot. Communication plan for each cutover (when, who, what to expect, how to escalate).
Performance baselines re-established. Application behavior validated. ISP failover tested. Documentation updated to reflect actual deployed state. Ongoing operations handed off to your team or transitioned to managed operations engagement.
Most clients transition from migration into managed SD-WAN operations — ongoing policy management, performance optimization, expansion to new sites. Migration projects typically run 3–9 months depending on site count. Operations engagements are open-ended.
Migration Patterns We Handle
Different starting points, same engineering discipline. These are the migration patterns we run most often.
National scope — SD-WAN migrations are primarily remote engineering work. California-headquartered, multi-site clients nationally. On-site visits are scheduled for cutover days at sites where physical presence helps.
Our Approach
No mystery. No black box. Every step is documented, explained, and approved before execution.
A complete risk assessment of your current network. Configurations reviewed. Segmentation validated. Gaps documented. You get a clear picture — not a sales pitch.
Address critical risks first, then build toward a standardized architecture. Every change documented, tested, and deployed without disruption.
Ongoing monitoring, change management, and architectural review. The network does not just work today — it evolves with your operations.
Your Engineer
Not a team of rotating technicians. Not a ticket queue. One named senior engineer who knows your environment, your compliance requirements, and your business context — from assessment through ongoing operations.
The person who designs your network is the person who maintains it. No handoffs. No abstraction. No loss of context when something breaks at 2 a.m.
Background: Founder, ex-Meta. Past engagements include Cisco, Wells Fargo, Fannie Mae, and other Fortune 500 networks — the same caliber of engineering, now applied to mid-market organizations.
Ambio Edge Networks works with industry-leading networking and security vendors to deliver the infrastructure your operations depend on.
Best-Fit Migration Profiles
The migration economics work best at certain shapes — multi-site with current circuit cost pain, or single-site with WAN reliability problems that broadband+SD-WAN can solve.
POS systems, payment networks, customer Wi-Fi, and back-office traffic across many sites. SD-WAN replaces brittle MPLS or ad-hoc broadband+IPsec setups. Application-aware steering keeps payment traffic on reliable paths even when broadband degrades.
EHR cloud reachability, secure remote clinician access, branch site reliability across multi-clinic operations. SD-WAN provides the hub-and-spoke or full-mesh connectivity to centralized clinical systems with the application-quality monitoring HIPAA-grade operations want.
Production-floor OT networks, warehouse-management traffic, ERP application paths to centralized data centers or cloud. SD-WAN provides the redundancy and application-aware quality measurement that production environments require.
Legal firms, engineering consultancies, accounting practices with multiple offices. SD-WAN consolidates branch connectivity onto a documented architecture — replacing the office-by-office setups that nobody documented and nobody can troubleshoot consistently.
Branch banking, financial advisory offices, fintech satellites. PCI-DSS-aware SD-WAN architecture isolates payment traffic, provides documented network controls auditors expect, and gives operations real visibility into branch network health.
Post-acquisition cleanup: consolidating multiple inherited branch-connectivity setups onto a single SD-WAN architecture. Often the fastest path to operational consolidation in a multi-vendor M&A environment.
FAQ
Project timeline depends on site count, complexity, and ISP procurement lead times. Single-site migrations run 4–6 weeks end-to-end. 5–10 site multi-site rollouts run 3–5 months. Larger fleets (20+ sites) typically run 6–9 months in waves. ISP procurement (broadband installs at new sites) is often the longest single dependency, which is why we start that early in the project.
No. We primarily migrate clients to Fortinet SD-WAN because that’s where we have depth, and the platform consolidation (SD-WAN + secure remote access + auth + Wi-Fi in one) eliminates a lot of operational overhead. But we’ll also work with Cisco Meraki SD-WAN, VMware Velocloud, Versa, and other platforms if you have a vendor preference or existing investment.
Most SD-WAN migrations involve adding broadband to sites that previously had MPLS-only connectivity. We coordinate that procurement: identify the right carriers per site (often two for redundancy), order the circuits, manage the install schedule, and handle the carrier troubleshooting before bringing the site live. ISP coordination is the part most internal teams underestimate.
For each site cutover: scheduled window (typically off-hours or weekend), parallel deployment running for 1–2 weeks before flip, on-site or remote engineer doing the cut, validation steps run, rollback path tested before any change is permanent. Post-cutover monitoring for 24–48 hours, then site is declared stable.
Common scenario. We design the rollout sequence so sites with circuits-ready-now go first, and circuits-arriving-later sites wait for their wave. The sequencing means you don’t lose project momentum; you just adjust the wave plan. This is a standard part of SD-WAN migration project management, not a setback.
Project pricing is fixed-fee per migration phase, based on site count and complexity. Single-site migration projects start around $5,000–$15,000 fully scoped. Multi-site rollouts (5–15 sites) typically run $30,000–$80,000 for engineering and project management, plus hardware and license costs (passed through). Real numbers come out of the assessment.
Start the SD-WAN Migration
Before any migration plan, before any ISP order, the first step is a real assessment of where you are: current circuits, traffic patterns, application dependencies, identity integration paths, site-by-site complexity. The deliverable is a written assessment with a recommended migration matrix. Whether you continue with us or not, the assessment is yours.
