Functional Verification

Prove the target system behaves correctly.

Run the origin and target applications through the same real journeys, then compare observed behavior before the modernization is complete.

Behavioral parity, observed directly.

Compilation and unit tests establish technical correctness. Functional Verification establishes that the behavior users and systems depend on is still intact.

The origin system is the baseline. Morph proves the target against it.

01 / Origin

Captures how the origin system behaves.

Morph runs relevant user and system journeys and records outputs, state changes, integrations, calculations, and side effects.

02 / Target

Runs the target system through the same journeys.

Morph observes the target under the same conditions, creating a direct comparison with the origin behavior.

03 / Evidence

Turns differences into actionable modernization work.

Failed comparisons return to the milestone. Passing comparisons provide evidence for review and approval.

Verification is part of every milestone.

The proof is connected to the approved plan and the work that produced it, rather than assembled after the migration.

01 / Plan

Establish the expected behavior.

Carry the behavior that must be preserved into the milestone.

02 / Execute

Run the target system.

Exercise the target application in its configured environment.

03 / Verify

Compare behavior and review evidence.

Resolve differences before the milestone is approved and merged.

Modernize the technology. Preserve the behavior.

Make behavioral evidence part of every milestone before the modernization is approved.
