I created a backup of my old company file (Company A) and copied it to my new company file (Company B).  I own an engineering firm and utilize progress billing for our projects.  Although all of the transaction appear to have transferred over to Company B, the estimates are not linked to the invoices which I previously billed (in Company A).  If I convert an estimate to an invoice, it does not take into account the tasks that were previously billed ~ it looks as if the whole contract is still available to bill.  Help!!!
