title: Migrating from IdentityServer3 to Azure Active Directory B2C
body: <p>We have an identity server that uses IdentityServer3 with ASP.NET Identity as the User Store. This is used by an AngularJS SPA app, mobile apps (Android and Windows) to access a web service built using ASP.NET Web API v2. This is a consumer facing application where users registers themselves and logs in to use our services. </p>
  
  <p>With Azure Active Directory B2C in preview, we plan to migrate to it in the near future. This is because we have a very small team and therefore we want to focus on our core application and outsource other services, i.e. the aforementioned. </p>
  
  <p>Can you help with pointers and best practices on how to migrate our users.</p>
