Can't upgrade Classical workspace to new workspace experience.



When I try to "Upgrade now" option of Advanced setting of "Edit workspace" pane, I get this error (see below Error message). Could you please help me with it - UnknownError is very vague, should I try to change some Tanent setting?


Thank you.



Error message:

Workspace upgrade failed
