So:
I believe I have to purchase either a JRiver Linux license or Master license for the QNAP?
I have a Windows license (MC22) and am told that a Master upgrade comes at a discount, how is this actually done? I don't see this covered in the order process anywhere.
I wasn't sure myself because I got myself an MC22 Master licence ahead of the curve. No matter.
1st step - check the licencing page (refer the bottom of every Interact page for a link) and as you indicate: no help there.
2nd step - head to the Windows MC22 sub-forum, where I spied the sticky:
Upgrade HelpYou could have also found the same basic info on the Wiki under
UpgradeThat at least answers some of your questions.
There is a key QNAP thread,
QNAP Instructions and Questions, that I think should be stickied to the top of the current version's board (in this case v21). Unfortunately it's not, so it took a bit of digging to turn it up.
You might find answers there. I leave further digging around to you.
