upgrade from 2.9 to 4.16

hi .. i have an RB 433 running on 3.30 and u need to upgrade it to 4.16 ..
my question is: i should upgrade my RB to v4…1st and then to v5… or i can do it directly to 5?

Waiting for your reply, thank u all

It is not possible run version 2.9 on RB433
RB433 started with version 3.0

always upgrade directly to latest version to avoid bugs in between versions. just remember that you will need to click the “update license” button immediately after you upgrade to v4 otherwise it will expire in 72 hours.
