# Software Migrations Safely move data and systems to modern platforms. --- ## How to engage FreedomDev for Software Migrations The path to safely moving from a legacy platform to a modern one with no data loss and no extended downtime. 1. **Inventory the legacy system** — Document every table, integration, custom report, and business rule embedded in the legacy system. Migration risk lives in what you do not yet know about. 2. **Design the target schema and migration plan** — Map every legacy field to its destination, design the cutover sequence, and decide what becomes one-shot ETL vs. ongoing dual-write. 3. **Run shadow migrations against production data** — Migrate against a copy of production data, run reconciliation reports, and surface every edge case before the real cutover. 4. **Cut over with rollback plan** — Cut over in a planned window with a documented rollback path. Run reconciliation post-cutover for a defined period until the migration is declared stable. --- ## Frequently Asked Questions ### Can you migrate our legacy system without downtime? Yes. We use a parallel-run strategy where the new system runs alongside the old one until validated. The cutover happens during a short maintenance window, typically measured in minutes. ### What if our legacy system has no documentation? That is common. We reverse-engineer the existing system through code analysis, database inspection, and interviews with your team. We document everything as we go. ### How do you ensure no data is lost during migration? We run automated validation scripts that compare source and destination data at every stage. Row counts, checksums, and business rule validation catch discrepancies before cutover. ### Can you modernize our application while migrating? Yes. Most clients take the opportunity to modernize the UI, improve workflows, and add features. We scope the migration and modernization as a single coordinated project. --- **Canonical URL**: https://freedomdev.com/services/software-migrations _Last updated: 2026-05-14_
