It's very easy. Follow these four steps.
Step 1. Throw away everything you developed as server jobs.
Step 2. Forget nearly everything you've learned about developing server jobs.
Step 3. Learn the parallel extender design paradigm.
Step 4. Using your original source to target mappings, develop parallel extender jobs under this paradigm.
I am deadly serious here. To get the best out of parallel extender, forget BASIC and learn to create BuildOps in C. Learn C/C++. Forget hashed files; they're not used in parallel extender. Learn the "right" way to do things. Get the Orchestrate manuals from Ascential Developer Network; they have more information than the DataStage Parallel Job Developer's Guide (though you need to read that, too).
To answer the next question, there are NO conversion tools.
Do it right the first time. Don't try to incorporate server job componentry; it's not worth it in the long run.
