Hi,  
We have custom database to migrate the users. We are trying to migrate the user to auth0 but it says user already exists. But when I search user with userid/username/email it doesn’t show user in auth0. I tired to unblock and delete user using userid/email still same error is returned. I am not sure what is causing the issue, can you please help to identity the root cause of the issue.

Thank you.

Hi @pmadala,

Welcome to the Auth0 Community!

I recommend checking out [this knowledge solution](https://community.auth0.com/t/user-already-exists-error-is-shown-when-trying-to-create-a-new-user-but-cannot-find-user-with-email-in-searches/120220) on the “User already exists” error that happens when trying to migrate users through your custom database.

Let me know if you have any questions.

Thanks,  
Rueben
