Legacy System Modernization.

Move off the old system without losing the years of work in it. We migrate without breaking — and without the year-long rewrite that ends in tears.

Why legacy is hard

The old system has years of institutional knowledge in it.

Every legacy system that's still running is running because it does its job. The data inside reflects years of real-world decisions, edge cases, and corrections nobody documented. A "rewrite from scratch" usually loses most of that — and ships a year late.

We prefer the strangler pattern: stand the new system alongside the old one, move workflows over gradually, and migrate data carefully with reconciliation at every step. The old system keeps working until the new one has earned the right to replace it.

Our migration playbook
  1. Inventory — what does the old system actually do?
  2. Map data — schemas, edge cases, the weird columns
  3. Stand up the new system alongside the old
  4. Migrate workflows in order of impact
  5. Reconcile data at every step
  6. Retire the legacy on a planned cutover
We've done this with our own products

PNB → ctAgency Suite™ is our own migration.

We're not theorizing. PNB has been in production for years. ctAgency Suite™ is its next-generation successor — and we're moving customers across the same way we'd recommend any client move: alongside, gradually, with full data fidelity. See ctAgency Suite™ →
