upgrade v.3.25 to 5.17

Hi!
I have Mikrotik RouterBoard 493 with OS v.3.25.Can I upgrade it to v.5.17?
Alex.

yes, you can. if you need any help, email support, we will help if any licensing issues arise.

I’d update to 3.30, do a “license update” in winbox, reboot, upgrade to 4.17, do a license update again, and it’s then ready to take 5.17. You may be able to go right to 4.17 and do a license update; I haven’t tried.

Sorry,but didn’t find e-mail of support.So may I post message here? I downloaded routeros-4.17.It has 5 directories,1 .iso file and 4 files.Which of them I have to copy in Files of router?

This is the correct file to download and copy to “Files”.
