Migration of assembler-programs.

Whenever you intend to migrate your existing assembler-programs to a 3GL or a 4GL, Bixoft will be pleased to help you (amongst others) with:

Another - though less apparent - option is migration to assembler. Even so, this is very well possible. Amongst others Bixoft can help you with:

For either type of migration way we would normally use the following checklist:

  1. Collect all functional requirements for the software product to be delivered - i.e. for the migrated program(s).
  2. Feasibility survey.
  3. Verify the correctness of existing documentation - if any - at the application level.
  4. Top-down create all required missing application level documentation, identifying main components: jobs, procedures, load modules, datasets and their respective functions.
  5. Feasibility study, building upon the results of the feasibility survey.
  6. Bottom up: identify all macros and programs, verify that nothing misses and verify version!
  7. Bottom up: create detailed documentation of function for each macro, program, etc.
  8. Extract business rules, detailed and complete description of functionality.
  9. Check whether results of the feasibility study need to be readjusted.
  10. Design replacement application and its constituent programs, code, test (Shadow production).
  11. If you can make it this far: time to celebrate the success.
