Migration Factory. Replacing a core is a migration decision.
Institutions do not fear new platforms — they fear conversions. The Migration Factory is A8 Core™’s disciplined path off a legacy system: profile, map, convert, reconcile, run in parallel, cut over, and prove it, with evidence at every gate.
The factory line
Each stage has entry criteria, exit criteria, and evidence.
Source inventory
Every system, file, and side spreadsheet that holds account truth, cataloged.
Data profiling
What the source data actually contains — gaps, conflicts, and surprises surfaced early.
Mapping & transformation
Field-level maps with rules, reviewed and versioned.
Document migration
Instruments, agreements, and statements migrated with indexing preserved.
Historical reconstruction
History rebuilt where the target model needs what the source never kept.
Trial conversion
Full-scale rehearsal conversions until the results reconcile.
Reconciliation
Converted balances and positions proven against the source, item by item.
Parallel run
Both systems live, compared daily, for the agreed proving period.
Cutover
A scripted event with go/no-go criteria — not a weekend of hope.
Rollback
A tested return path until the exit criteria retire it.
Decommissioning evidence
The record that the legacy system was retired with data accounted for.
Migration pathways
Source families the factory is designed for.
Legacy trust accounting
Trust systems with principal-and-income books and instrument files.
Custody platforms
Positions, lots, and open transfers across custodians.
Retirement recordkeeping
Account, contribution, and beneficiary histories with tax context.
Loan servicing
Notes, schedules, escrow, and delinquency states in flight.
Portfolio management
Households, models, and billing histories.
