What are the pitfalls when upgrading corporate laptops (windows 7/8/8.1 pro) to windows 10?
Will there be licensing issues?

Answer 1

If you update the licensed OS, then there will be no stones. On the Microsoft website, everything is written about the license and other things.

Answer 2

Yes, windows10 is, in principle, one big pitfall of small soft ones.

Answer 3

On an employee's Toshiba laptop, the employee himself updated Windows from seven to ten. The hard drive crashed. Type writes damaged and Windows does not start. He was bought a new hard in the service. He put seven litsuhu then again up to ten. And again the same bullshit. As a result - the hard one is not dead, it's just that Windows is messing with the hard one there .. it still sits on the seven, dreams of a ten.
