We made that exact transition, and the limitation you describe is real - you can’t get anything out of GA, particularly at the granularity you’ll have with an alternative. So it’s best to start early, because it’s a slow process. It’s even slower if you don’t instrument the right events in the beginning, because you’ll wait a while to gather enough event data to perform an analysis, find you want to track some new event, and then need to wait even longer to have enough data for analysis. It can be frustrating, and a surprising amount of work. If you want to build out your BI infrastructure in the mean time, you could always ETL your e.g. server logs into the data warehouse as a stopgap. It’s definitely not the same as the customer-centric setup that you get with Segment, though, unless you have some advanced logging already set up.
