Data Migration is a process of moving required (and most often very large) volumes of data from our clients' existing systems to new systems.

Existing systems can be anything from custom-built IT infrastructures to spreadsheets and standalone databases.

Data conversion can be defined as a process of converting data from one structural form to another to suit the requirements of the system to which it is migrated.

Approach used for Data Conversion:

1. Conversion Data Mapping ( map to specify the data of legacy system with  data of oracle ERP system ).
2. Download Programs ( programs to extract data from database and insert into the Flat file ).
3. ASCII Flat File (Flat file / Text file).
4. Upload Program
5.Interface Tables
 a) Description of Interface Table.
 b) Creation of Interface Table.
6. Translation Programs
7. Interface Programs
8. Application Production Table
9. Testing
10. Write and Perform Conversion Execution Plan.
