I’m quite new to this, so apologies if this is a stupid question. I recently got a QNAP TS-459 Pro+ secondhand, and it’s no longer supported softwarewise by QNAP. That makes it incompatible with a lot of modern software. Is there any way to either forcibly update the OS or change it out entirely? I’d love to actually be able to control the machine I own
unplug it’s internal DOM (disk on memory - look it up)
then boot installation from USB stick of desired OS - you might have problem with fan control (old docus: https://www.cyrius.com/debian/kirkwood/qnap/ts-41x/tips/)
