Guides stay short on purpose. Deployment, Docker, and pilot grids live on shared pages — not here.
Why teams move now
- Talent cliff. The people who wrote the batch are retiring.
- MIPS / ops cost. Batch data work is cheaper on a lakehouse.
- Copybook fear. REDEFINES and ODO block manual rewrites — automation is the path.
Hardest construct — sanitized peek
Enough to judge fit. Not a rebuild-the-parser cookbook.
Before 05 AMT-X PIC X(12). 05 AMT-N REDEFINES AMT-X PIC S9(10)V99. After (databricks) # Typed fields from copybook (conceptual) # Program logic → PySpark job
What good looks like
Parser-driven conversion, readable databricks output, and row-level parity before cutover. Upload a sample or run a pilot on your estate — no email gate to peek.
Next step
Try a curated sample, then price your estate. Book a call only for guided / air-gapped needs.
