Many of us have been using these things for years, but upgrades always seem to extend past all memory of setup problems. The nature of the beast methinks.
That's why it would be *so* useful if the manufacturer anticipated expansion issues such as the need to retain userid 98 and groupid 98 when directly copying to new disks. A simple NASlite livecd maintenance tool would do it.
Boot the CD, then just drag and drop between disks (old and new).
Yes, have just received my permissions kicking after moving all those disks with a standard puppy live CD. Have only 4TB more to go (rolling eyes).... Puppy made it soooo easy to screw this up. Fast, easy, mounting of the piles of drives transferred. Too bad it didn't work

Why should server elements consider something like this? Does it make *more* sense to turn every purchaser into a linux guru? Or is that something more efficiently handled by those who can probably compile in their sleep?
Prospects buy these these licenses as a cheat. It's faster/more efficient to pay than it would be to learn/debug/develop. Good trade. Time for cash.
*Guarantee* other customers will face this problem with the current street price of 2TB fixed firmly at $85. And once you get to such sizes, underpowered hardware lacking gigabit makes that disk to disk transfer real attractive (if dangerous).
I mean...how could your company add the godzillion protocols you now support without coming up with something for your more knuckle dragging customers who faithfully avoided any hardware "not simple CIFS"? It must have been very difficult to shoehorn all that stuff in. But NASlite "scent marking" a standard livecd with your assigned permission data is not in the queue? Geesh.
