Azure AD B2C | Seamless Migration

Hi
I want to migrate users from a system to Azure AD B2C. I want to know the steps or ways to achieve this.
I tried the bulk user create using csv but that allows only onmicrosft.com domains (verified domains).
I need to migrate users with any username such as gmail outlook etc or even phone numbers.

Please help

Hi @AbhayChandramouli-2076 • Thank you for reaching out.

For user migration, below are the 4 options that you have.

  1. Just in time migration v1 - In this sample, Azure AD B2C calls a REST API that validates the credential, and migrates the account with a Graph API call.

  2. Just in time migration v2 - In this sample, Azure AD B2C calls a REST API to validate the credentials, return the user profile to B2C from an Azure Table, and B2C creates the account in the directory.

  3. Seamless-account-migration - Where accounts have been pre-migrated into Azure AD B2C and you want to update the password on the account on the initial sign-in. Azure AD B2C calls a REST API to validate the credentials for accounts marked as requiring migration (via attribute) against a legacy identity provider, returns a successful response to Azure AD B2C, and Azure AD B2C writes the password to the account in the directory.

  4. B2C to B2C Migration - Migrate users from one B2C instance to another using just-in-time migration.

Please go through these samples to identify the one that best addresses your requirement.

Hi @amanpreetsingh-msft ,
thanks for the answer,

These are custom policy based. Is there a way we can migrate the users beforehand ? and not use the Azure built in login page ?
Our scenario is something like this
We login into "our" login page and then use these credentials to create(if not exist)/update the user in Azure AD B2C using graph APIs.

@AbhayChandramouli-2076 • In that case, you can use the Graph Call provided here: Create a user with social and local account identities and to combine multiple requests for bulk user creation, use JSON Batching.

Hi @amanpreetsingh-msft ,
1.So json batching and csv are the only ways available to migrate users ? And what about my question on the different domains I would like in the userPrincipalName which is not allowed in CSV method ?
2. I am able to register users with any domain email / mobile via the user flow login or custom policy login, but how to bulk create users with different domains ?


Thanks
