Dear all…
Can any one tell me how to upgrade mik OS 2.9.51 TO v3.11 or more than that…
plz help me out…
thanx
copy new files( http://www.mikrotik.com/download/all_packages-x86-3.16.zip ) to MT ftp server and reboot.
First check ‘system license’ and make sure that it says “Upgradable To: v3.x”.
If not then you need to buy a new RouterOS license.
If it is allowed then you can just drag the correct upgrade file to the files area using Winbox and then reboot.
You find the upgrade files here:
