Shell style

We’re current;ly on 10.1.400 and all users use the Classic shell style. Because it was what they were used to when we jumped from V8 to E10. (I always go for shallow learning curves.)

We’re upgrading to 10.2.300 soon, and was wondering if there is any need to get users to use the modern shell or even active homepage.

Should I expect some near future version to not support Classic shell?

The last time I checked, ATE requires the Classic Shell.
