GA4 migration services address the technical and strategic challenge of moving from Universal Analytics's session-based data model to GA4's event-based architecture. While UA was sunset in July 2023, many businesses still have GA4 properties that were set up hastily during the migration period — configured in parallel with UA without the deliberate event schema design that GA4's flexibility requires, resulting in properties full of inconsistently named events, missing parameters, no custom dimensions, and conversion configurations that were copy-pasted from UA without considering how GA4's different data model changes what events should be primary key events. Our GA4 migration service addresses both migration scenarios: for businesses that still need to properly configure their GA4 property after a rushed parallel setup, and for businesses building a new analytics infrastructure on GA4 for the first time. We begin with a current-state review — documenting your existing GA4 property (or UA configuration if migrating from scratch) to identify which goals should map to GA4 key events, which custom dimensions need to be created, and what event tracking was in UA that needs to be recreated in GA4's event model. We produce a migration mapping document that explicitly connects each UA goal and event to its GA4 equivalent, and implement the full GA4 configuration based on that mapping. Historical context documentation explains which GA4 events correspond to which UA metrics so your team can maintain analytical continuity across the data discontinuity that the UA-to-GA4 transition introduces.
