System Conversion is the process of changing from the old system to the new one. Conversion from one information system (IS) to another is common in all organizations, regardless of type, size or location. On the information technology (IT) side, conversion can involve hardware, operating system (OS), database management system (DBMS) and the database it supports, and/or application portfolio.
