Did GA4 replace Universal Analytics?
If you have an existing Universal Analytics (UA) property, your new Google Analytics 4 property did not replace it; instead, a GA4 property was installed in addition to UA and both collected the data simultaneously until June 30, 2023, when UA data collection stopped.
Do I need to do anything if I have a properly set up GA4 property?
Your GA4 property is already active and collecting data. You do not need to do anything regarding data collection going forward.
If you had a Universal Analytics property that you used for analysis, you may want to consider saving historical data for the periods not covered by your GA4.
What do I need to do if I only had a Universal Analytics property?
In June 2023, Google added support of Google Analytics data collection using Universal Analytics code snippet. It automatically created GA4 properties to collect that data. If you have a single UA tag snippet installed on your site, and don’t recall creating a GA4 property, you are likely collecting GA4 data through the UA tag.
If you had your GA4 conversion handled automatically by Google, you may consider switching from UA tag to Global tag (GTAG) snippet on your site. Follow these instructions starting with Step 3.
Your other option is to install a GTM tag on your site, which you can cofigure to send the data to your existing GA4 property. A Google Tag Manager (GTM) tag is more powerful and flexible, but the initial setup is more complicated. GTAG is simpler to install and it offers basic GA4 functionality. My guide to tags will help you decide which one is better for you.
