Venus OS Updates and Nodered

Quick question about the Venus OS v3.75 (or later)

Does updating the OS version disrupt all Node-Red flows and settings?
Would I possibly lose my N-R setup having to re-install everithing or is it safe to update at any point now and in the future?

Thanks everyone

All config is maintained.
It is always a good idea to keep an export of the flows in case of emergency, but never had an issue.
There is also a backup copy so you can boot from the older version if there are issues.

Thanks, I have all flows backed up at all time however the same cannot be done for the GX devise as I understand nor for other Victron devices.
