Upgrade RouterOS v3.30 to newer

RouterOS General
1

Hi,
I found one old RB 133, where was Router OS v2.x. I upgrade it to 3.30 and I want to uphrade to newer version, but i still see:

 > system license print
    software-id: "#hidden#"
  upgradable-to: v3.x
         nlevel: 4
       features:

I upgrade license key but RouterOS is still upgradable only to 3.x

What I must do for upgrade to higher version of RouterOS, please?

I upgraded few RB133s from 3.30 to higher version in the past and don’t remember any problem with the process. I don’t know what “upgradable to” field said, but it upgraded just fine. The only required extra step was upgrading software id to new eight-character format. So if you already have that, just upload new packages and reboot. If it doesn’t work, there’s always Netinstall.
