About This Service

What Is GA4 Migration?

Migrating from Universal Analytics to Google Analytics 4 requires more than creating a new property. It requires rebuilding your measurement strategy from the ground up because UA and GA4 use fundamentally different data models, and replicating UA structures in GA4 produces configurations that misuse the platform and generate poor-quality reports.

A proper migration maps your existing UA conversion goals to GA4 key events, rebuilds your custom event taxonomy using GA4 naming conventions, reconfigures your Google Ads conversion imports, and updates any custom reporting that depended on UA metrics. Historical data cannot be migrated, but measurement continuity going forward depends on getting the GA4 setup right.

Adslytics handles GA4 migrations with a parallel verification phase before cutover so your team can compare UA and GA4 data side by side, identify discrepancies, and resolve them before relying on GA4 exclusively. Deliverables include a migration audit, configured GA4 property, and full documentation.

What Clients Say

"We'd been running GA4 for six months with barely any useful data — missing events, broken funnels, no purchase data. After the audit and rebuild we finally have accurate revenue figures and a proper conversion funnel. Completely transformed how we report."

Sarah Kim

Head of Marketing

"The GA4 migration from Universal Analytics was blocking our whole reporting stack. The team handled the full migration, set up matching custom events and built us a Looker Studio dashboard that replaced our old UA reports within days."

David Marsh

Growth Manager

"Our GA4 was technically installed but 90% of the custom events we needed weren't firing. After the setup service we have scroll depth, video plays, form submissions and checkout steps all tracking correctly. Now we can actually optimise."

Lisa Park

Marketing Director

FAQ

Frequently Asked Questions

Real answers to questions we hear from clients before starting a GA4 Migration project.

Ask Us Anything →

Yes — many sites still have misconfigured GA4 from rushed migrations and need a clean rebuild to get accurate data.

UA stopped collecting data in July 2023. Historical UA data remains in your UA property for export but cannot be moved into GA4.

The metrics are not directly comparable due to the different data models. We document the differences so you can interpret changes in your data correctly.

We reconfigure Google Ads conversion tracking to use GA4 key events, ensuring your campaigns continue to optimise correctly.

We map each UA goal to the equivalent GA4 conversion event and verify each one fires correctly in the new setup.

Typically 3–5 business days for a standard website migration.

Many UA custom reports have GA4 equivalents. We document the translation or rebuild them in GA4's Explore tool.

GA4 uses audiences and explorations rather than segments. We recreate your key UA segments as GA4 audiences or exploration filters.

If you use Looker Studio, Data Studio, or other BI tools connected to UA, those will need to be reconnected to GA4.

We migrate custom dimensions to GA4's user and event-scoped custom dimensions with equivalent data capture.
