Teams jump straight into rebuilding dashboards without mapping what they're actually leaving behind. No data source inventory. No capacity plan based on real workload. Row-level security that exists as "separate report copies" in the old tool, never translated into actual RLS roles. Business logic buried in Tableau calculated fields or Qlik set expressions, rebuilt by eye instead of documented first.
Three weeks after go-live, finance flags a number that doesn't match the legacy system. Nobody can explain why, because nobody wrote down what the old calculation actually did.
The fix isn't more QA at the end. It's a discovery sprint at the start: inventory, logic docs, capacity sizing, security mapping, all signed off before anyone touches a visual.
Migrate in waves. Run parallel reporting. Catch the mismatches while they're cheap.
