This phase will provide Computer System Services with the necessary knowledge of the characteristics of the source information system, its environment and its components. The technical choices for migration in the target environment will be evaluated according their opportunities in this context as well as the different constraints given by Client.

Conversion Migration speeds up and simplifies the overall definition of the migration project by producing an inventory of all objects to be transformed.
The Conversion Migration system will keep a complete inventory of all sources, data files and databases to be migrated. This will ensure that all is known and that all of these objects are migrated.

Using the Conversion Migration inventory, the number and complexity of procedures, programs, transactions, screens, reports, databases, tables and files are carefully identified, as are program translations and any special considerations ( house-made access methods and modules) .
