How to upgrade Flow?

Hi Marco, I currently own professional v.2.3.0. How do i upgrade to version 2.4.0? Also i have highly customized my flow interface, nuendo group structure, expression maps, generic remotes and vep midi output routings and audio outputs to accomodate a surround sound setup i use. Will I be able to selectively install any bug fixes etc that version 2.4.0 includes so as to keep the many hours/weeks of work that has gone into personilzing my setup. Finally could you confirm that the latest version of o-s-c will work fine with my setup (macbook pro m1 max) I am currently using version 1.15.7 due to stabilzation issues you mentioned a while ago but just wondering if all is good to update now. Thanks. Paul.

Any update on this Marco please? Thank you.
