Loadusers to modify users RM data

Our users currently have a numbered RM account and a named RM account, we are ready to move to the numbered account only so we need to add their named RM info to their numbered account, items such as groups, roles, change to checkLS yes, email, portalrole, workflow user if they are an WF approver, and also created their requester identity, they already have an employee identity.  I have modified the ldusers.pl addiding the fields I need and the requester identity.  I am receiving lots of errors when I run the "perl ldmssusers.pl managerloadusers.csv".  So my questions are:  am I on the right track?  Can the loaduser create the requester account and populate the workflow field in RM?
