These posts also offer alternate options:
- use analytics service in TFS/Azure DevOps optionally combined with PowerBI/PowerBI Server. You can embed these in Sharepoint.
- use dashboards in TFS/Azure DevOps
- use markdown/wiki to cross link between Sharepoint and Azru DeOps
Your existing ShasePoint sites need to be unlinked from TFS, the widgets will stop working. Your document libraries etc will just work as they always did.
