Enterprise-Grade
Ecommerce Migrations

From fragile builds to future-proof stacks.

We don’t just move your store. We evolve it.

Whether you’ve outgrown your current platform or need a custom build to support your next stage of growth, migrating or rebuilding your ecommerce site is not a small project. There’s data to protect, systems to connect, and other continuity to maintain every step of the way.

At Command C, we approach migrations and builds not just as technical tasks, but as critical business transition. Our job is to make the process feel less like a leap of faith, and more like a natural evolution.

Our migration and build process is designed to:

  • Minimize Risk: We begin with a strategic technical roadmap designed to optimize your data, identify opportunities for automation, and understand your goals so we can anticipate future technical requirements.
  • Enhance Performance: We optimize our builds for accessibility, conversions, and back end efficiency.
  • Avoid Downtime: Where possible, we build in parallel, so you’re never flying blind or losing sales.
  • Deliver Confidence: You get proactive communication, transparent tradeoffs, and a reliable partner from start to finish.
  • Empower Your Team: We design and build systems your internal team can actually manage, reducing friction, time, and dependency on developers.

Two Core Migration Paths

One end goal: a stable, scalable foundation built for growth.

Most ecommerce replatforming projects fall into one of two paths, each with distinct tradeoffs, timelines, and outcomes. During our strategic technical roadmap, we guide you toward the right fit based on your goals, constraints, and future vision.

Optimized Theme Build (Our Most Common Path)

Faster to launch. Easier to evolve. Built on a sound technical foundation.

This path uses a thoughtfully selected pre-existing Shopify theme, tailored to your needs and customized where it counts. It’s ideal for brands that want to modernize operations, improve UX, and avoid reinventing the wheel. We lead with functionality, structure, and scalability, then layer on design, not the other way around.

What it includes:

  • Strategic theme analysis and selection
  • Prioritized customizations based on business goals
  • Clean product data structuring and migration
  • Integration with 3rd-party systems (ERP, 3PL, etc.)
  • UX improvements without costly delays

This is how we help 8-figure brands future-proof their tech without overbuilding or getting boxed in.

Custom Design + Custom Theme Build

When your brand expression or CX requires complete design control.

We occasionally lead full custom builds when a pre-built theme can’t support the vision or complexity required. In these cases, we collaborate with your internal team or a design partner to ensure the build aligns with a solid technical foundation, without letting aesthetics lead at the expense of structure.

What it includes:

  • Full discovery-led functional specs and technical plan
  • Coordination with design partner or your internal team
  • Pixel-perfect frontend matched with backend integrity
  • Clean data migration, integration, and performance optimization
  • SEO and performance-focused build process

We only recommend this path when it’s clearly justified by brand or functional demands—and we help you weigh that decision upfront.

A Process Built for Peace of Mind

Our step-by-step approach to high-stakes projects:

  1. Strategic Technical Roadmaps
    We audit your current ecosystem, uncover risks, and align on goals and scope.
  2. Parallel Build (Where Possible)
    Our team builds and tests your new environment in a staging environment. No downtime. No guesswork.
  3. Migration & Launch
    We move over your data, set up redirects, run quality checks, and go live with confidence.
  4. Stabilization & Support
    We monitor performance, fix edge cases, and provide post-launch support to ensure a smooth transition.

Outcome: A Site Built for Now—and for What’s Next

Our Migrations & Builds process ensures you launch with clarity, confidence, and room to grow:

  • Continuity: Maintain revenue, SEO, and backend processes throughout the transition.
  • Customization: Get exactly what your team needs—no more, no less.
  • Scalability: Build a foundation that won’t buckle as you grow.
  • Alignment: Launch with a site that reflects your business priorities—not just what’s easy to implement.

We’ve helped dozens of high-volume ecommerce teams make the switch—and they’ll tell you: it’s not just the end result that matters. It’s how it feels to get there.

Before making the platform switch, we had server problems, blocked traffic—it was frustrating for us and our customers. Since Command C changed our platform and set us up properly, it’s been much easier. I’m relieved to finally be getting back to the work I enjoy!
