Changing a business-critical platform without breaking anything

Situation

A live global integration with Getty needed to change while existing publisher behaviour continued to work. A technically correct migration would still have failed if it disrupted partners or forced an abrupt transition.

Context

The platform was already carrying real production responsibilities. Compatibility, availability and partner trust mattered alongside the desired change, and a single irreversible cutover would have concentrated too much business risk in one moment.

Decision and approach

The change was designed around staged rollout, testing and reversibility. Existing behaviour was preserved while the new path was introduced and observed. Compatibility was treated as a product obligation, not cleanup work. Rollback and kill-switch thinking created a route back if evidence from production differed from expectations.

Outcome

The integration could change without sacrificing business continuity. Risk was reduced through controlled exposure and recovery options, while publishers retained the behaviour they relied on during the transition. No single release had to carry all of the uncertainty.

Lessons and principles

Major live changes are safer when reversibility is designed in from the start. Compatibility buys time, staged rollout produces evidence, and a reliable escape path protects both the platform and the relationships built around it.
