Mainframe → ERP
Everyone stops
at the edge of the chasm.
Two ways have been tried for thirty years. Both fail before the far shore — then Palm builds the bridge that holds. Palm is the only platform built for the mainframe-to-ERP crossing.
The crossing
Every rule docks with lineage
The ferry hauls it whole, unopened — and founders mid-chasm. The zipline sprays guesses across — seven in ten never land. So Palm surveys the shore and builds the bridge.
| route | what arrives | lineage |
|---|---|---|
| The re-host ferry | The complexity, intact and sealed | — |
| The LLM zipline | Guesses — arrived 30%, unsourced | 0% |
| The Palm bridge | Every rule docked — arrived 100% | 100% |
The last mile
Why the bridge holds
An ERP cutover fails for one reason above all: the rules inside the mainframe were never truly known. Re-hosting ships them sealed — the complexity arrives intact. Generic AI ships them guessed — about 30% arrive true, none with a source. Either way, you discover the truth in production, at the worst possible moment.
Palm inverts that. Palm Key maps every dependency on the near shore. Palm Ark extracts each rule deterministically, with the exact source lines it came from. Palm Ray redesigns them for the target — fit-gap against Oracle Fusion, SAP, Workday or Salesforce’s own model, with test cases and compliance evidence attached.
That is a redesign, not a translation — and it is the difference between a cutover you schedule and a cutover you survive.
