Mikrotik - Upgrade RouterOS from the Command Line

My Mikrotik router was running version 6.30 which I needed to update to version 6.31 in order to support RSA keys. I found updating the router from the command line to be quite easy an straight forward. it only requires a few commands and requires little user input. I know of two ways to view the current running firmware. My hAP at the time it arrived was running RouterOS version 6.30.4.

Making use of the /system package update check-for-updates we can also view the running version and latest available version of RouterOS for download.

[admin@HM-GW] /system package update> check-for-updates

   current-version: 6.30.4
   latest-version: 6.34.3

Now that we know there is an available update we tell the router to download and install. The router will reboot.

Installing the new firmware took less than a minute. Let’s check again and see what version of RouterOS is currently running.

We are done and the system is now updated to the latest available firmware. Fairly easy and painless to update RouterOS. 4/8/2016 - Corrected grammatical error. Thank you for pointing it out.
