Massive Upgrade of RouterOS

Dear Specialists.
Is there a way to Upgrade ther outerOS in many routerBOARD at the same time??? I mean, without entering through winbox each time/each router.
We have about 25 units working (routerBOARDs and x86) and Upgrading them becomes a bit cumbersome.
I thought NetInstall could do it but NO.

Thank YOu very much.

First there is “auto upgrade” under system (never tried this feature).
Second - you can upgrade using Dude http://wiki.mikrotik.com/wiki/Upgrading_RouterOS_with_Dude

I’ll also add that you can use SSH to execute a /tool fetch command on each remote router to pull in files via FTP to each device. This could be scripted in one location and executed once to effect multiple devices.
