Document migration
Migration Is Not the Same as Conversion
Conversion creates outputs; migration also governs inventory, validation, exceptions, reconciliation, rollout and long-term stewardship.
The safe operating rule
Preserve the source. Label extraction and inference. Keep unknowns unknown. Record warnings and failures. Reconcile every batch.
What UD does not claim
No perfect conversion, 100% OCR accuracy, compliance preservation, legal equivalence, accepted archival-standard status or freedom from manual review is promised.
