Hi @ammo,
Migrating users who authenticate via Single Sign-On (SSO) from a legacy system to Auth0 requires a different approach than migrating users from a database. Direct import or creation of users into an SSO connection is not a standard feature in Auth0. Instead, the platform is designed to provision these users “just-in-time” (JIT) when they first log in through the federated identity provider.
The only thing that needs to be addressed is any metadata about the users that needs to be transferred. For that, a custom solution might be required.
If you have any other questions, feel free to reach out.
Have a good one,
Vlad
