It depends on how Google handles your specific LSA migration. Don’t assume that all of your old LSA reporting will automatically appear in the new Google Ads setup. Some historical data may remain available through the original LSA interface or account history, while the migrated campaign may use a different reporting structure.
Before migration, save or export important data such as spend, leads, cost per lead, lead types, and performance by date. That gives you a clean baseline for comparing performance after the transition.
You should also keep records of your old settings, service areas, budgets, and lead-quality data. That way, even if the reporting changes after migration, you can still compare the new campaign against your historical LSA performance.
