Failed to Get Transition Error

Hi, We use Innovator SP9. We customized Express ECO workflow and Lifecycle. Now we get "failed to get the transition to promote the Part from Preliminary to Preliminary." I searched on the FORUM and I understand that I should change the Part Lifecycle. We did not make any change on Part Lifecycle yet. Can somebody please help me how to update lifecycles and solve the problem? thank you in advance.
