Warning! File migration tool will trash all unsaved work.

[TecsolAus]

In my case, the mandatory file system change icon is placed almost on top of the view rotation tool, inconveniencing normal work until the upgrade is done.

The implication is the file change is related to Autodesk's cloud storage system, and no suggestion it affects the work in progress. If the action required by Autodesk is initiated, all unsaved work is trashed!

There is no warning to save first.

This has been reported as a support ticket.

Thanks for pointing this out for other customers. It's always a good idea to save your designs regularly.
