B2C2B2CMigration

JIT Migrate from one B2C Instance to another

Disclaimer: This sample is provided AS IS - a best effort will be made to update this sample as the service evolves.

This sample solution demonstrates how to migrate users from one B2C instance to another using Just In Time (JIT) Migration. The policy will check to see if the user exists in the current tenant, and if they exist then the normal authenication process is followed (login-Noninteractive). If the user does not exist within the curren tenant a seperate Remote login call is made to the legacy B2C instance using ROPC. On successfull Authenitcaion to the legacy tenant, the user details (including password) are written to the local Tenant.

On next login the user will exist in the tenant so the normal authenticaiton process will be followed.

The following diagram illustrates the migration flow:

To configure this solution, you will need to use Azure AD B2C Custom policies that use the Azure AD B2C Identity Experience Framework. Review the getting started with custom B2C applications: https://docs.microsoft.com/en-us/azure/active-directory-b2c/active-directory-b2c-get-started-custom?tabs=applications

This example builds upon the Social and Local Display Control Starter pack sample which can be found here - SocialAndLocalAccounts
