An Umbraco instance has two users: OriginalUser NewUser I have migrated to this instance to a new server (including the database from SQL server to another SQL server).

I took notes of the email and password of OriginalUser when I created this Umbraco. Now, I cannot log in as OriginalUser. I reset the password with the password reset link sent by email, and everything looked fine except that I am still unable to log in with the new password. I can log in as NewUser without any problem. When I log in as NewUser, I see only one user - NewUser - in the Users tab.

Could anyone shed some light on this?
