Produce evidence that the control works
Build a compatibility and data-reconciliation plan for the real application. Preserve important business semantics while removing unsupported runtime assumptions. Avoid a migration that merely moves the same unmaintained code into a new hosting account.
Your immediate priorities
- Test custom extensions, scheduled jobs and external callbacks against the target runtime or replacement.
- Reconcile representative products, orders, customer records and redirects before a controlled cutover.
How to work through the decision
Work in the approved environment and keep secrets out of tickets, logs and chat. Record the artifact or configuration being tested, the expected behavior and the observed result. Test rejection of unauthorized access alongside successful business behavior. Preserve enough evidence for another person to review the conclusion, while minimizing sensitive data. A passing smoke test is one observation, not proof that every exposure path has been eliminated.
Evidence to ask for
A tested migration or upgrade path with measurable acceptance and recovery criteria.
Which hidden behavior will fail only after customers start using the replacement?
Work with the next person
Return a reproducible verification record to the technical manager, including untested paths and assumptions. Identify the operational owner of any follow-up test that cannot run during the immediate change window.
Continue with the technical manager report for this topic.
A scenario to rehearse
Illustrative exercise, not an observed customer incident: A custom discount extension prevents a runtime upgrade. The exercise compares changing that behavior with continuing emergency maintenance, while preserving order history and a reversible cutover plan.
What a useful outcome looks like
A tested migration or upgrade path with measurable acceptance and recovery criteria. Keep the decision dated and return to it if new evidence changes the scope.
