Thanks @d-cunnings
USMTGUI works great and is immensely simple to use.
We did have a small snag as we did not want Onedrive and Sharepoint (neither the local users folders or OneDrive settings) migrated as the users log in to the same OneDrive account after being migrated to AAD.
But the developer fixed that in just a few days. The latest USMTGUI 11.25.22H2.4 version (May 23) now handles this correctly and bring over all the browser favorites, Desktop, links to recently opened files etc.
The users we tested on are now much more confident being moved over.
