If you create the address data with a new customer number, all existing certificates with the old customer number and address data will be displayed in the CBW and retained, as will the certificate pdf. The newly created certificates are then displayed with the new address and the new customer number (as well as the pdf). Thus, the certificates for both customer names and both customer numbers are displayed in the Certificate Explorer. (Existing certificates with old data and newly created certificates with new data and new customer number). This may be necessary if the Customer is in a transition period trading under the old and the new name. But having a Customer under 2 Names with valid certificates should be limited to the necessary period of time.
