Hi,
I'm new here.
I tried to upgrade my classic workspace to modern, but I got an error.
Do you know why it's happening?
Here's error description:
Underlying Error AdalMultiFactorAuthRequiredErrorCode
Hi @asnyk33 ,
I got the same error today when trying to upgrade from classic to modern workspace. I believe it was giving error because our company has Duo two factor authentication. When I used another account without having to enter the second authentication then I was able to upgrade. Give it a try.

Hi , @asnyk33
Will similar situations occur in the upgrade of other classic workspaces?
Maybe you can refer to this articles to delete possible related policy:
