Best Practices for Migrating from a Homegrown Feature Management Solution

Migrating from a homegrown feature management solution to Unleash involves a strategic approach to ensure efficiency and reduce complications. The process includes defining the scope by separating old and new feature flags, creating a business case to secure resources, and planning the migration by understanding use cases, core feature flag setups, key stakeholders, and system architecture. It emphasizes the importance of not making app modernization a dependency and instead focusing on the immediate benefits of feature flags. Real-world examples, such as a major US-based e-commerce firm and a large UK bank, highlight the challenges and successes of scaling feature flag migrations, including dealing with large volumes of stale flags and maintaining security compliance. The process is aided by Unleash's flexible architecture and tools, ensuring a smooth transition with minimal impact on existing operations while paving the way for improved development velocity and innovation.
