Modernise your customer & partner identity platform and prepare for the retirement of Azure AD B2C with Microsoft Entra External ID.
Azure AD B2C is now deprecated and will reach full end of life in May 2030. Organisations must migrate customer and partner identity estates, from simple login solutions to complex, highly customised journeys, to a modern, scalable, secure Microsoft identity platform.
This solution is designed for organisations that:
- Use Azure AD B2C today and require a supported future platform
- Have complex custom policies or bespoke customer journeys
- Need to migrate external identity data at scale (tens of thousands to millions of accounts)
- Are using a competitor platform (Okta, Autho0, ForgeRock, Ping) and want to consolidate onto Microsoft Require flexible branding and end to end control of user experience
- Must meet specific compliance standards
- Want to streamline operations by bringing external identity into Azure & Entra
- Has external portals or digital services critical for customers, partners or citizens
“Condatis is a Microsoft Partner specialising in External Identity and Access Management (IAM), integrating Azure B2C into new and existing technology. They have worked with some of the largest enterprises and government departments globally always delivering the results that we expect from our partners. The team at Condatis show their passion, dedication, and competency every time we engage with them, whether it’s bringing them into a customer engagement or when we look for some thought leadership in this space. I would have no hesitation recommending Condatis as your IAM specialist partner to ensure a successful deployment.”

Business Challenge / Context
Workforce identity is now central to security, productivity and compliance yet most organisations face the same barriers:
Azure AD B2C is going away
Azure AD B2C is fully retiring with an end-of-life date set for May 2030. After this point, the service will no longer be available, meaning every organisation must migrate.
External journeys are complex and critical
From account creation to multi step onboarding and verification, any migration must be zero disruption.
Not a Simple Lift-and-Shift
Azure AD B2C → External ID is not a like for like transition. Many custom user journeys, UI customisations and API integrations cannot be directly migrated.
Competitor IAM Platforms are Costly and Fragmented
Some solutions often require additional tooling for UX, fraud controls, custom flows and integration patterns.
Branding and UX Expectations are Higher Than Ever
Organisations need flexibility that is not always available out of the box in External ID.
Our solution
Condatis helps customers migrate from Azure AD B2C and competitor CIAM platforms through three approaches:
Path 01
Solution: Microsoft Entra External ID (Out of the Box)
Approach
Use External ID directly for authentication with standard journeys and screens
Best for
- Low/medium external user volumes
- Basic authentication flows
- Simple branding needs
Migration Method

Licensing / Costs
External ID free for first 50k MAUs
Path 02
External ID + Custom Extensions

- Custom journeys
- Strong branding/UX needs
- Integrations with internal/external
Migration Method
External ID + Condatis custom components

Azure hosting
Our migration process
No matter the path, our delivery structure is consistent and transparent:
01 Identify Requirements
Analyse existing journeys, policies, UX, data, identity providers, and compliance needs.
02 Develop MVP / Validate Approach
Prove architectural direction (Path 1, 2 or 3).
03 Parallel Running
