Modernize legacy code in bounded slices
Characterize current behavior first, then move one seam at a time with compatibility checks and review.
What does this modernization workflow workflow cover?
Characterize current behavior first, then move one seam at a time with compatibility checks and review.
What should an evaluator inspect?
Inspect the stated requirements, workspace boundary, validation evidence, approval points, and stated deployment scope rather than inferring results from an example workflow.
Is this customer proof?
No. Workflow pages describe an evaluation model and may use fictional product artifacts. They do not assert customer adoption, outcome, or availability evidence.
Can we run this workflow today?
A released self-managed artifact and tested quickstart are not published. Review the self-hosted requirements or register interest in future Cloud or Enterprise offerings.
What is the next step?
Use the ungated sample run and pilot scorecard to frame the evaluation, then choose a request path only if the operating model fits.
Starting condition and desired outcome
A legacy component has weak tests and hidden consumers, making a large rewrite difficult to verify. The outcome is one reversible modernization slice with recorded behavior and compatibility evidence.
The current manual workflow
The BranchRunner workflow
- 01Characterize behavior
Capture inputs, outputs, consumers, and baseline checks before editing.
- 02Choose one seam
Define a bounded replacement and explicit non-goals.
- 03Implement compatibly
Change the isolated seam and preserve an adapter when required.
- 04Compare and approve
Run old-versus-new checks and review the remaining migration boundary.
Evidence produced
The run keeps claims separate from checks and decisions. The evidence below describes the record, not a guaranteed outcome.
Product example. Repository, checks, and identities are illustrative; configure them for your system.
Where a person stays in control
A person approves which behavior may change.
Known inconsistencies are recorded before work begins.
Any intentional difference requires a decision.
Legacy code is removed only after its consumers are evidenced.
What the workflow can produce
Integrations, deployment, and edition fit
Validate the workflow against one real repository
Bring the starting condition, required checks, and approval boundaries. We will identify what can be configured today and what remains deployment work.
