Tally.Developer 9 Release 5.0 is designed to help you to seamlessly migrate customisations developed for earlier releases of Tally.ERP 9 to Tally.ERP 9 Release 5.0. It helps in identifying areas where the customisations may potentially fail or may deliver altered behavior in the enhanced language platform.
