OS update between two lumia devices

[Windows Central Question]

One of my Lumia 650 and Desktop is upto date. But another Lumia is running a very old version of windows 10.

Is there a way to share the os update from other devices to my Lumia 650?

Any update has to be downloaded. No way to share.

Nope.
