Transitioning from a legacy platform to Statsig involves a series of strategic decisions and technical preparations tailored to streamline workflows, reduce technical debt, and promote testing democratization. The process is not merely technical or automatic; it involves comprehensive change management, including taking inventory of existing metrics and data sources and deciding which elements to migrate. Important considerations include whether to maintain or eliminate feature flags, the necessity for automation, and the integration of current data systems with Statsig's capabilities. The transition is designed to be flexible, with no obligatory cut-off from the old platform, allowing teams to adapt at their own pace. Statsig offers support for various data integrations and provides tools for migration, especially for those coming from platforms like LaunchDarkly. Additionally, insights into A/B testing, experimentation culture, and the historical evolution of web experience platforms highlight the broader context in which Statsig operates, emphasizing the importance of a strong testing infrastructure and learning from both successes and failures.
