Can I use the micro SD I have made for my Pi 2 on my new Pi 3?

[Necrobot20XX]

I just got a Pi 3 in and took my micro SD card from the 2 and put it in the 3. It shows some boot screens then nothing but black. I put the SD card back in the Pi 2 and it still works. I have tried an OXMC SD card I made months ago on the Pi 2 in the 3 and it worked fine. I don't want to start from scratch because of all the work I put into customizing Recalbox on the Pi 2 and adding all those roms. I keep a backup of the SD card image to prevent problems but I just can't figure out what to do.

How i know the pi2 Image is not compatible with a pi3.

For the future i think this is a good and easy way:
https://github.com/recalbox/recalbox-os/wiki/Use-an-external-usb-storage-device-on-recalbox-%28EN%29

With this method, system (on SD card) and share (on USB device) partitions are separated. So if you have to reinstall your system, you'll keep your user data. You'll have just to select your USB device in the recalbox, and your recalbox will be ready to play.

@abunille I specifically bought 32 gb micro SD cards for my Pis. For one, I don't have extra usb drives that size around. Another reason is so I don't need to carry around another device , that also will use another usb port by the way, for easier travel and uses less space. There has to be a better way. I don't understand why the SD cards aren't compatible with the different Pis. The downloads and operating systems are the same. I'm not good with coding or anything like that, I just use my Pi for Recalbox and Kodi.

maybe exist a workaround for your problem, i dont know.

In the downloaded zip file of recalbox there are installation files for pi1,2,3.
When starting your pi, the system recognizes which hardware is present and takes the appropriate installation package. And your installation was on pi2.
The pi versions differ SoC (Broadcom), CPU, architecture, ...

Indeed each recalbox version is builded with specifics settings from each RPI (as said by @abunille different cpu using different instructions, etc....) and some emulators are specifics to a RPI version (other rpi not powerfull enough to emulate a system, like dreamcast, psp that are rpi3 only etc...)

Hi the Pi's are different (built in Bluetooth and wifi) and the Recalbox operating systems are totally different for each version of the Pi.
You will never be able to swap the microSD's over.
As for the usb sticks taking up space, I recommend the Samsung microfit range of usb sticks. Absolutely tiny.
Google them, or, here is a link to one on Amazon https://www.amazon.co.uk/gp/aw/d/B013UVGX2E/ref=mp_s_a_1_3?ie=UTF8&qid=1503052821&sr=8-3&pi=AC_SX236_SY340_FMwebp_QL65&keywords=samsung+32gb+usb+memory+stick&dpPl=1&dpID=517KHugrmYL&ref=plSrch

Thanks for the info, I'll try to find the best / easiest way for me to move the roms and themes and stuff over.

Does a customized config file, controller schemes, and box art get transferred with usb as well? Or would I have to redo all of that?

Have you read the wiki entry?
https://github.com/recalbox/recalbox-os/wiki/Use-an-external-usb-storage-device-on-recalbox-%28EN%29

"recalbox/share" is then on your usb storage

Just read it. Says, roms, saves, bios, ect. Doesn't say anything about custom controller configs, scraps, python scripts, altered config.txt, or anything else I changed on my system. Would that come along as well, or would I expected to have to redo those parts. Thank you.
