Is a 2 step upgrade possible from Vista to 10?

Question

Windows

There is a computer with a license sticker windows Vista home basic OEM, respectively, the system is installed the same.
Now I plan to upgrade both the hardware and software parts.
With iron, everything is clear and understandable. Question about the "free" upgrade to Windows 10.
It will not be possible to upgrade directly. Is it possible to update in 2 stages:
1. Vista --> 7
2. 7 --> 10
In theory, it seems to be possible, but 2 questions arise:
1. How feasible is this in practice?
2. If it is possible to implement what status will the product key have?
Rolling 10 from scratch and breaking it is not difficult. An interesting issue is the preservation of the license.
ps It is possible to roll Vista from a disk under a native key, so as not to drag all the trash into win 10.

Not

Answer 3

The key for whist is not suitable for the seven. After the upgrade, the seven will ask to change the key, refusing to activate automatically. After upgrading to 10, the behavior will be similar.
