As you may be aware, a new Windows analytics solution has been released in preview called Desktop Analytics few months ago (see https://t.co/VqQV4WRj83).
Desktop Analytics is aimed to replace the well-known Windows Analytics which has been here for quite some time through 3 Log Analytics solutions: Upgrade Readiness, Update Compliance and Device Health.
If you are using Windows Analytics, it is time for you to prepare and move to Desktop Analytics as Windows Analytics will be retired by January 31, 2020.
From the 3 solutions above, only Update Compliance will remain available.
To prepare your migration from Windows Analytics to Desktop Analytics you can use the documentation available here https://docs.microsoft.com/en-us/sccm/desktop-analytics/faq#existing-windows-analytics-customers and start using the new Desktop Analytics portal (https://aka.ms/desktopanalytics).
When setting up your new Desktop Analytics, don’t forget to enable the option “Do you want to see inputs from Windows Analytics?” if you want to get your existing data from Windows Analytics to be migrated
