What is the difference between data conversion and data migration?

Data Migration is upgrading from one version to another version fro e.g. from 11.5.9 to 11.5.10.. Data Conversion is receiving data from a legacy system or receiving data from another module ( e.g. PA), validating it and converting it to ur our the target module using the standard import program.

Are there any Migration tools  that can make the job easier. What are the steps.

Data Conversion refers to the movement of data from a legacy system or application, to a replacement application or sub-system.

Data migration refers to movement of data from one database to another database, but not neccesarily to a working application or subsystem tables.

Other important terms pertaining to data include;

2.Data Integration

3.Data replication

4. Data Intergrity Testing

5.Data Transfer

6.Data Transformation

7.Data Translation

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.
