As outlined in our Data Transfer policy, Auth0 does not support transferring data between accounts at this time. You can export users from your account using the Management API v2, or the User Import/Export extension, however users will need to reset their passwords in the new account.
Another option is to setup your new account using a custom database connection with import mode enabled, to migrate users from the old account into the new account, as they sign in. This would be a seamless migration, without requiring them to reset their passwords.
