Migrating from a homegrown SSO implementation to WorkOS

Transitioning from a homegrown Single Sign-On (SSO) solution to WorkOS aims to simplify and streamline the process of managing SAML and OAuth/OIDC integrations, reducing maintenance burdens and enhancing reliability. This guide provides a step-by-step approach for organizations to migrate their existing SSO systems, whether they have fewer than 15 connections or a larger number, by either reconfiguring each connection individually or using a proxy method to facilitate incremental migration. It emphasizes the importance of auditing current setups, documenting configurations, and choosing the appropriate migration path based on the number of connections. For smaller setups, direct reconfiguration is suggested, while the proxy approach is recommended for larger systems to avoid customer-side IdP changes. The guide details the technical implementation steps, such as setting up callback and initiation endpoints, creating organizations in WorkOS, and using the Admin Portal for IT admin self-service. It addresses handling connections that require customer reconfiguration and outlines a decommissioning strategy for the old SSO implementation once all connections are successfully migrated. Ultimately, adopting WorkOS is presented as a means to enhance SSO reliability, reduce maintenance, and provide additional features like managed certificate renewal, error handling, and observability through the Events API.
