In our organization we have BO running on Netezza database for few years now , now we are upgrading to Teradata . In this process we are planning to modify tables and columns due to adopt to new changes and merging with other line of business .
we have few thousands reports are already running on Netezza with existing database structure. Is their a way to update the reports using backend process to change the columns in reports rather than re designing the reports.
Any help is appreciated .
