Migrations are operating-risk events because they rewrite definitions, ownership, and habits.
Teams often treat a migration as a technical cutover: move fields, validate counts, train users, retire the old system. Necessary, but not enough. The bigger risk is that the new system changes what objects mean, where authority sits, and how people get work done.
A CRM migration can change account hierarchy. A billing migration can change invoice states. A product analytics migration can redefine usage events. An HRIS migration can alter employee status rules. Even if every record moves, the operating meaning may not.
The systems-of-record work should happen before migration weekend. Which facts will the new system own? Which old fields are being retired? Which copied fields become authoritative, and which lose authority? What happens to historical comparability? Which workflows need new reconciliation paths?
Operators should also watch for temporary truths that become permanent. Migration spreadsheets, mapping files, manual overrides, and exception logs are useful during cutover. If they remain the only place a decision is documented six months later, the migration created a shadow system.
A good migration plan includes a post-cutover truth audit. Check duplicate records, hierarchy breaks, sync failures, permission mismatches, stale dashboards, and workflows still reading from the old source. Then assign owners for cleanup.
The technical question is whether the data moved. The operating question is whether the company still knows where truth lives. Both have to pass.
This is part 8 of 10 in Systems of Record.
