Transition from Bolt with the customer journey moving every week

Begin with ownership and telemetry, then extract the capability whose boundary can be tested in isolation—often reads, notifications, or a single workflow. Introduce an adapter so the existing Bolt UI does not need to know which implementation answered. Promote the new path with a small cohort, compare outcomes, and only then move the next dependency. Each slice should have a removal date for its temporary bridge.

Choose a single writer for each entity and use explicit read routing; never let two databases silently diverge. Add idempotency keys, an outbox or equivalent event record, replayable reconciliation, and a flag that can send eligible traffic back. Test timeouts and partial failures, not only matching 200 responses. The goal is a recoverable overlap, not two systems that look healthy until a refund or email is duplicated.

App-store ownership belongs in the company’s developer organization with role-based access, backup administrators, signing material, package identifiers, privacy answers, and a release calendar. If Bolt produced a web-first product that later gains a wrapper, decide who owns the binary pipeline before promising a mobile date. We require a dry-run submission and emergency fix path before the old delivery process is retired.

Put a named operator on point in US Central, publish the dashboard and escalation tree, reserve a release freeze, and give support a concise explanation of what changed. Watch conversion, auth, error rate, job lag, and provider callbacks by cohort. The handoff is complete when the person covering that week can diagnose a failed new-path request without waiting for the original Bolt builder.
