Yes. However, deleting your Universal Analytics property may in some instances affect your Google Analytics 4 property. If you reused your Universal Analytics tagging to send data to your GA4 property, deleting the Universal Analytics property may stop data flow to your GA4 property, and you’ll need to set up a new Google tag. Learn more about the Google tag. Proceed with deletion of your Universal Analytics property only if you’re certain you no longer need data to flow to your GA4 property or other configured destinations.
For Google Analytics 4 properties that rely on Universal Analytics tagging for data collection, there is no additional risk when those Universal Analytics properties are shut down and deleted by Google. Once Google deletes your Universal Analytics property we’ll automatically continue to use your Universal Analytics tagging for your Google Analytics 4 property, however only if your UA tags are still on your website. If you decide to remove your UA tags, you can replace them with a Google tag.
Google Analytics 4 has replaced Universal Analytics. Starting July 1, 2023, standard Universal Analytics properties stopped processing data. (360 Universal Analytics properties with a current order will receive a one-time processing extension ending on July 1, 2024.)
Starting March 2023: If you didn't manually migrate your active standard Universal Analytics property to a new Google Analytics 4 property and didn't opt out of an automatic property creation, we created a Google Analytics 4 property on your behalf. Automatically created Google Analytics 4 properties reuse existing site tags whenever possible.
Starting July 1, 2023: Standard Universal Analytics properties stopped processing hits, including standard properties in accounts that also contain 360 properties. Some properties continued to process data for a short period after this as we staged the shutdown of Universal Analytics. You'll be able to access your previously processed data in your Universal Analytics property until July 1, 2024.
I've exported some high level reports + cleaned up/removed various legacy analytics properties that I had in my accounts. There're seemingly only 3-4 remaining to actually convert to GA4 now:
There is a need to update from the old 'Universal Analytics' to the new 'Google Analytics 4':
