I found an old guide that basically said something along the line of updating the old 3DS to the latest firmware, updating the second 3DS' emunand to the latest firmware, and doing a system transfer from the old sysnand to the new emunand. My problem with that is, the latest firmware isn't supported by emunand, so I haven't even bothered with it yet. Am I just stuck until 9.5 emunand is supported by Gateway?
