Application migration | Firemind
Application migration

The mapping first.Then the target.

An application read from its source, mapped component by component, and rebuilt for its new home as a reviewable pull request.

Mapping delivered first
Endpoint-by-endpoint contract table
API contracts preserved
Single pull request
Cross-cloud
Proven on our own applications
The problem

Application migrations stall on the mapping.

Which handler serves which endpoint, which table holds which key, which identity provider issues which token. Until that is written down, nothing can move safely.

The IT Operations Engine reads the application from its repository and writes the mapping first. Then it produces the target.

What has to exist before code is written

  • An architecture mapping produced from the source, not from memory or a diagram nobody has updated
  • An endpoint-by-endpoint contract table, so nothing silently changes shape in the move
  • A decision per component on whether to lift and shift or rebuild, made from evidence
  • The original API contracts preserved, so the consumers do not have to move at the same time
  • One pull request your team can review, apply and cut over on its own schedule
How we approach it

Read the application, write the mapping, generate the target.

The engine reads the application from its source and produces an architecture mapping and an endpoint-by-endpoint contract table before writing anything. It then generates the target. Infrastructure code, backend, frontend and CI/CD pipelines, with the original API contracts preserved. All of it lands as a single pull request for your team to review, apply and cut over.

We have done this on our own applications, across cloud providers. On yours, we would prove it on one application first and scope the rest from what that shows.

What lands

    • The mapping, before anything else - An architecture mapping and an endpoint-by-endpoint contract table, produced from the source itself. It is the first deliverable, so you can check it before a line of target code is written.
    • The generated target - Infrastructure code, backend, frontend and CI/CD pipelines, generated for the new home with the original API contracts preserved. Where a service has a native equivalent in the target, we use it.
    • One reviewable pull request - All of it lands as a single pull request. Your team reviews it, applies it, and decides when the cutover happens. The engine produces the migrated codebase and the evidence, not the go-live decision.

How it starts

One application, chosen with you.

The mapping is delivered first so you can check it before any code is written.

  • Choose one application

    One application, chosen with you, on the basis of what it will prove rather than what is easiest to move.

    • Scoped with your engineers
    • Source repository read directly
    • Nothing generated yet
  • The mapping, delivered first

    An architecture mapping and an endpoint-by-endpoint contract table, produced before anything is written, so you can check it against what you know.

    • Which handler serves which endpoint
    • Which table holds which key
    • Which identity provider issues which token
  • The target, as one pull request

    Infrastructure code, backend, frontend and CI/CD pipelines, generated with the original API contracts preserved, landing as a single pull request.

    • Native equivalents used where the target has them
    • Review and apply on your schedule
    • Cutover stays your decision
What stays with you

Review, apply and cutover.

The engine produces the migrated codebase and the evidence. Your team decides when it goes live.

You gain:

  • The mapping tells us whether lift and shift or a rewrite is appropriate for each component.
  • Where a service has a native equivalent in the target, we use it.
  • We have done this on our own applications, across cloud providers. On yours, we prove it on one first.

Start with one application and its mapping.

Choose an application with us. The mapping and the contract table are the first deliverable, and you can check them before any code is written.

Your benefits:

  • Mapping first - delivered before any code is written.
  • Contracts preserved - consumers do not have to move with you.
  • One pull request - reviewable in full, applied by your pipeline.
  • Proven on our own - applications, across cloud providers.
