Migration off Ember

Sometimes the honest recommendation is to leave. Hiring has become the constraint, the addon ecosystem no longer covers what you need, or the org has standardized on another stack. When that's the call, the difference between a migration that ships and a rewrite that dies is the strategy.

Our position: incremental only

We do not run big-bang rewrites. The failure pattern is well documented: the rewrite team chases a moving target while the old app still needs fixes, the business loses patience around month nine, and you end up maintaining two half-apps. Every migration we run keeps one production app serving users throughout.

What the work looks like

• Strangler-route strategy — the route is the natural seam in an Ember app. We move leaf routes to React, Vue, or Svelte one at a time behind a routing boundary, so each increment ships to production and retires real Ember code.
• Shared foundations first — authentication, session handling, design tokens, and a shared component vocabulary get settled before the first route moves, so the two stacks look and behave like one product.
• Parallel-run discipline — moved routes run against real traffic with error and performance budgets watched, and a working rollback path until confidence is earned.
• Sequencing that respects your roadmap — low-churn routes move first; screens under active product development move last or stay put until the churn settles.

When we'll talk you out of it

If the assessment says the app is healthy and the real problem is solvable with upgrades or staffing, we'll say so. A migration is years of engineering spend — it should happen because the numbers support it, not because the framework stopped being fashionable.
