In the User form, change the password to say '123456' (any string you desire) and ask the user to login with the new password you set and the next screen will ask the user to change his/her password.
Thanks...Is this expected behavior... We need to reset for all users after the migration. Any option to login with old password as source.
Yes this is a expected behavior, users will have to change the password upon their first login.
