I will migrate azure ad b2c to microsoft entra external id

Yes. Existing Azure AD B2C customers can continue using the service. I can assess whether maintaining the current platform, using phased coexistence, or migrating to Microsoft Entra External ID fits your applications and business requirements.

Yes. I can review, troubleshoot, and improve existing Identity Experience Framework custom policies. I can also assess how their logic could move to External ID. Some custom policy capabilities require redesign because one-to-one feature parity is not guaranteed.

Yes, after an assessment. The right approach depends on user volume, password requirements, applications, custom policies, and acceptable coexistence. Options can include bulk user migration, password reset, or a staged credential migration pattern.

I design the migration to reduce disruption through staged testing, controlled application cutovers, validation, and rollback planning. The final risk and maintenance window depend on your applications and migration method.

No. Microsoft licensing, Azure consumption, domains, certificates, third-party identity services, and paid development tools remain the client's responsibility.

Yes. I can review or implement OAuth 2.0 and OpenID Connect integrations, MSAL authentication, protected APIs, application registrations, token claims, and supported federation scenarios.

Yes. Organizations can deploy fully branded login pages on custom domains with dynamic query string support, responsive UI, multi-language localization, conditional UX, and identity branding for mobile and web apps. This is essential for businesses building white-label CIAM, custom authentication UX

The Premium package includes integration with your existing app using MSAL (Microsoft Authentication Library). I'll provide working code samples and configure the redirect URIs, scopes, and token validation. Full app development is outside scope but I can guide your developers through integration.

Yes, this is covered in the Premium package. B2C supports seamless user migration (lazy migration on first login) and bulk migration via the Graph API. I'll design the migration strategy based on your user volume and password hash format.
