I currently have the latest gnoboot on my xpenology, if I switch to nanoboot on the usb stick, will my drives be safe when I switch them over? I have most things backed up already but not everything as I dont have the space.
I would wait till then new version comes out. All you have to do is flash your usb stick and chose upgrade
from the HP when it gets to the nanoboot screen. Oh and download what version of Synology you need first.
