Per what's discussed in this article:
I'd like to switch the sites we set up with the URL prefix verifcation over to the Domain verifcation for a more complete data collection.
In my head the process would be:
example.com+ update txt record for domain verification.
My concern is data loss from removing the URL prefix added properties.
Will the data we collected with the URL prefixed sites still be intact when it's added via the Domain Verification?
