Microsoft Stream: IT admin-led migration tool to move videos from Microsoft Stream (classic) to new Stream (on SharePoint)
The Stream migration tool helps admins migrate video and audio files and related metadata from Stream (classic) to new Stream (on SharePoint). With this tool admins can select some, or all, video and audio files in Stream (classic) and then move them to SharePoint folders, SharePoint site collections, or specific OneDrive folders. We expect the migration tool to start rolling
out under public preview in late August and to GA in November.
