Migration of existing systems for interoperability

A system may still serve its users while its technology becomes difficult to maintain. Replacing it risks losing working behaviour and years of information.

How this work runs.

The run as one route: which tools get involved, in what order, and where the chain is not mechanised yet.

One run, start to finish. A box with an accent tick is a tool acting and opens its own page; a rounded box is an artefact or a record; a diamond is a decision the work cannot pass without. A dashed line is a hand-off the suite has not mechanised yet.

sends a scoped job
A job sent to the tool that does it, with its limits written in. What comes back is a record of the result.
reads what the other publishes
Nothing is sent. The next tool reads what the one before it has published, at the moment it needs it.
adds to a running record
A new entry on a record that only grows. Whoever needs it reads it later, and neither side waits.
hands over a task
A piece of work still owed, with an owner and a next step. It stays open until someone closes it.

What this work delivers.

A rebuilt system on a maintainable framework, with its existing behaviour checked and its historical data reconciled.

  1. Record the baseline

    Inspect the running system, its users, its data and the behaviour people depend on.

  2. Plan the migration

    Choose the target framework and map existing constructs to it. Identify gaps and changes that need an owner’s decision.

  3. Rebuild and reconcile

    Forge rebuilds the application while Scribe maps legacy data to the target structure.

  4. Check the result

    Verify behaviour and data fidelity before the owner approves release.

Migration is appropriate when the software itself needs to change. A system that works well may need only a data mapping or connection.
