I manage a deployment of teacher and student iPads in a middle school as well as one grade level in the high school. We're hovering around 1,300 devices and I organize the pre-stage enrollments by class for students and by building for the staff. For example, I have my student groups as student-gradyear, such as "student-2021" for my 7th grade. Staff is simply staff-building, such as "staff-dms." So right now we have six groups total. It makes it easy to generate smart groups based on those specific pre-stage enrollments and assign inventory attributes relevant to that group.
As far as how I handle the Apple DEP side of things, I simply upload the batches by the pre-stage enrollment they need to go in. For example, this summer I uploaded 350 iPads for the class of 2021 then went into the pre-stage enrollment, confirmed that I had 350 unassigned devices then simply assigned all of them to that enrollment. Uploading everything at once would make too tedious to separate them into the individual enrollments.
