RT-AC68U firmware upgrade question

hello all, apologies if I'm not posting in the right place

I have a 68U that is running 3.0.0.4.384_81049 currently, was thinking of upgrading to at least 3.0.0.4.385.20633.

Are there any pre-requisites or can I go straight to 3.0.0.4.385.20633 without issue?

Thanks in advance!
