    To answer your first question, all data stays intact when downgrading. You'll only lose data if you brick your 3DS, but I think that goes without saying.

    As far as the manual transfer goes, I'm not aware of anyone doing it between two different regions.

    It'd be more interesting to see what happens when transferring from Japanese to US/Eu, since there are a number of Japanese exclusive puzzles.

    So if I then went on to install emuNAND once it has downgraded (making sure I swapped out SD cards when emuNAND is formatting) could I still have access to the Mii Plaza data?

    Yes, you won't lose either the installed version neither the saved data (unless you get a lot of softbricks requiring you to format the unit before updating).
    And I think that this tutorial you linked won't work with Mii Plaza data, since it's saved on 3DS internal NAND memory. I've had to switch SD cards twice that I hadn't the chance to backup their data and then when I've redownloaded Mii Plaza updates (and spotpass data) all the save data for puzzle swap and DLC games were recovered.

    Also when you do a NAND dump and use it to create emunand this data will be also carried over to emuNAND, so when you format your sysNAND only the sysNAND will lose progress.

    Hey, so I'm pretty confused about this. Most all of the tuts that I followed to downgrade one of my consoles told me to format. I dumped my sysnand as a .bin and made a backup of my original SD. Had to format both when unlinking nand. So I restored the SD backup and when I relinkd NNID to my emunand, i got my mii back but NONE of my plaza data puzzles etc. What did I do wrong? What should I do differently on my other console?

    I started the whole process again yesterday on a freshly downgraded N3DS 9.2.

    Once I had dumped the NAND I took out the SD card and copied everything over to PC. I then let emuNAND format the SD card and I left it last night copying my files back over from the PC onto the SD card.

    I will finish the process off later tonight and will let you know if I keep my Mii Plaza data!

    If you are only trying to set a emuNAND for CFW or doing a downgrade, doing a system format isn't necessary.
    I've done downgrades on 6 O3DS units over the weekend, none of them softbricked so I hadn't to format them at all, the plaza data were preserved on those units' sysNAND.

    When I've setup Gateway/rxTools emunand for those consoles, I only had to format the sysNAND (to unlink sysNAND and emuNAND) after I've finished setting up the emuNAND, so the plaza data were carried over the emuNANDs. After I've finished setting up the rxTools I removed the SD card from those 3DS and performed a system format on sysNAND, after I've done it I used Ninjhax (you can use browserhax) to setup menuhax and when it booted into emuNAND there was the Mii Plaza with all pieces that were collected, no losses at all.

    On the case that you lost the "Nintendo 3DS" folders on your SD (like when my SD cards corrupted) you only have to redownload the mii plaza update (either through CIA or eShop), activate spotpass and let the console redownload the puzzles images, the progress itself is written at the console NAND, not your SD card.

    TL;DR: If you performed a system format before dumping the NAND you will lose mii plaza data. If you dumped the NAND before doing a system format and used it to set the emuNAND, the Mii Plaza progress data will be preserved.

    Really glad to hear that, because this is what I was thinking. I will not be formatting the console until after the NAND dump with the plan that the data would then be carried to emuNAND. I will make sure to remove the SD card is removed before the system wipe to unlink NANDs.

    Thanks!

    Just to confirm that it worked perfectly. 9.2 emuNAND and all of my MiiPlaza data intact!
