Dŵr Cymru Welsh Water replaced their mainframe-based Customer Accounting System applications with a commercial off-the-shelf (COTS) solution running on Windows. However, regulatory requirements mandated that at least seven years of customer billing data was to be archived and accessible at all times, a request which the COTS solution was unable to accommodate. As a result, three IDMSX databases containing all seven years of required historical billing data were left in place on the mainframe to meet the requirement, to be accessed as needed. Learn how Modern Systems came in, converted the IDMSX databases to a single SQL Server database, migrated the applications used to access the data to Windows, and helped Dŵr Cymru Welsh Water shut their costly big iron down for good, in less than four months.
