Yes, you can format emunand on the new one and go emuNAND -> emuNAND or sysNAND -> emuNAND. In both cases, they need to be on the latest firmware (unless you can spoof eshop). Choose options that say wireless data transfer because if you remove the SD card from a console running emuNAND it will crash. Also, delete any CIAs or eShop content you don't need, because it's incredibly slow and if you have too much stuff it won't work (my system transfer didn't work the first time, but worked after I removed all the games I didn't think I'd play again). You may encounter a bug where the system transfer seems to be completed from the source system, but when you boot into emuNAND on the target system, it says it still has to complete some process and is stuck. To solve this, turn off wireless in sysNAND, before you boot into emuNAND, and then when you boot into emuNAND it will give you the option to abandon the system transfer. Choose that and you'll be allowed to get out of System Settings. Now access the eShop on your emuNAND, let it sign you in, then get back out. All your purchased eShop content will magically appear before your eyes. Good luck!
