Plan your Azure AD B2C migration to Microsoft Entra External ID.
Customer identity environments often span custom policies, applications, user journeys, authentication methods, domains, branding and monitoring. Without a clear understanding of these dependencies, migration can disrupt sign-in experiences, create security gaps and increase delivery risk.
The Entra External ID Migration Assessment is a focused two-week engagement that reviews your current Azure AD B2C environment and maps what needs to move to Microsoft Entra External ID.
The assessment considers applications, integrations, users, authentication, custom policies and supporting dependencies. It then defines a practical migration path covering priorities, risks and the key decisions required before delivery begins.
Reduce migration risk by understanding your Azure AD B2C environment, dependencies and technical considerations.
Protect the user experience by planning the transition of users, authentication, MFA, branding and domains.

Strengthen customer identity foundations with Microsoft Entra External ID.
Microsoft Entra External ID is a customer identity and access management platform for securing access to external-facing applications. It supports customer sign-up and sign-in experiences, identity management, authentication and application access controls.
Not necessarily. Microsoft states that existing Azure AD B2C customers can continue using the service and will be supported until at least May 2030. Organisations should still assess their environment early so they understand their dependencies, options and appropriate migration timeframe.
An assessment should review applications, integrations, custom policies, user accounts, authentication methods, passwords, MFA, domains, branding, monitoring and legacy dependencies. It should also identify migration risks and define a practical sequence for moving to Microsoft Entra External ID.
