I have exported my user list from a Microsoft AD connection from a tenant, and I’d like to import those users into another tenant.
When I log into my other tenant and go to import, I cannot select the AD connection even though I have connected it to an application. It doesn’t show up in the drop down list. I went to export just to see if the connection would show up and it did. Why is it showing up in exports but not in imports?
You can only import users to database connections. Please see our doc on bulk user imports: Bulk User Imports
You could import the users to a database connection and implement account linking. Then, during the first time login of the Azure AD connection users, those users can be linked to the Auth0 database users for those accounts.
