Update question

[aitch-zed]

Hello, I would like to update my Sansa Clip Zip rockbox to 3.14 version as it has better battery time.
My current rockbox version is from 2015.
Is it enough to simply replace .rockbox folder with lastest version from dev builds page, or do I need to do more complex stuff ?

Just copy a new . rockbox folder on top of the old one.
