Google Sites Migration + Transition Website
Google is retiring classic Sites and replacing it with the new Google Sites. Owners of University of Minnesota classic Sites have until November 30, 2021 to migrate to the new Google Sites. Starting December 2021, any remaining classic Sites will be automatically downloaded as an archive and replaced with a draft in the new Sites experience for site owners to review and publish.
The Office of Information Technology website has a detailed migration timeline and instructions on how to migrate classic Google Sites.
