Transition from Softgen while the product keeps answering users

Start with inventory and telemetry on Softgen’s critical journeys, then extract the seam you can test alone—often server-side secrets and auth callbacks, then the write API, then DNS/origin. Keep Softgen UI behind an adapter so screens do not need to know which backend answered. Promote each Softgen-to-owned slice with a small cohort, compare outcomes, and delete the Softgen bridge on a dated schedule.

Yes, if each entity has one writer. Softgen must not keep mutating records your destination also owns. Use idempotency on Softgen-era forms, explicit read routing, and a flag that returns eligible traffic to Softgen only for read-only fallback. Test Softgen OAuth redirect dual-allowlists and webhook signature dual-verification—not just matching 200s—before you call the overlap safe.

Deploy ownership belongs to the company’s CI and hosting accounts, not Softgen’s preview publish button. Name who can cut Softgen DNS, rotate Softgen-era secrets, and freeze Softgen-side schema changes. Softgen remains a temporary origin until the destination proves path parity; Softgen’s publish flow is retired only after rollback from the new origin is rehearsed.

Put a named operator on Softgen-and-destination dashboards, publish escalation for auth and 5xx on Softgen-migrated paths, and give support a short note on what still routes through Softgen vs what does not. Watch Softgen cohort conversion, session errors, and SEO crawl anomalies on the paths Softgen used to own. Coverage is done when that person can diagnose a Softgen-era failure without opening Softgen’s editor.
