 * [Require InnerSource before Open Source](/patterns/1-initial/innersource-before-open-source.md) - *Maintaining and managing open source projects can be challenging for organizations, due to a lack of internal infrastructure and people with the knowledge of the required collaboration practices. By requiring projects to be InnerSource before becoming open source, teams have time to establish the necessary internal support, governance, and collaboration skills needed for successful community engagement.*
 * [AI Code Generation Context](patterns/1-initial/ai-code-generation-context.md) - *AI tools generate code that diverges from project standards and architectural patterns. Provide an AI Code Generation Context within the repositories to guide AI tools in producing contributions that align with existing project conventions, reducing review friction and maintaining code consistency.*
 * [InnerSource as a Career Booster](patterns/1-initial/innersource-as-career-booster.md) - *Many employees wonder how contributing to InnerSource projects benefits their careers beyond their immediate team objectives. By engaging in InnerSource, individuals expand their skills, grow their network, increase visibility across the organization, and unlock new career opportunities.*
+* [Migrating from InnerSource to Open Source](patterns/1-initial/migrating-from-innersource-to-open-source.md) - *TBD*
