The system transfer process is mostly the same as it would be done without CFW on either device, but you will need to use faketik at the end to restore any applications and games that did not come from the eShop.
What You Need
The latest release of GodMode9 (the GodMode9 .zip file)
Copy GodMode9.firm from the GodMode9 .zip to the /luma/payloads/ folder on your SD card
Copy the gm9 folder from the GodMode9 .zip to the root of your SD card
Reinsert both SD cards into their respective consoles
Section II - NAND Backup
Creating a NAND backup of both consoles is a good idea in case something goes wrong. It ensures you can recover your data in the event of an error.
For both consoles, perform the following steps:
Press and hold START, and while holding START, power on your device. This will launch GodMode9
Press HOME to bring up the action menu
Select "Scripts..."
Select "GM9Megascript"
Select "Backup Options"
Select "SysNAND Backup"
Press A to confirm
This process will take some time
If you get an error, make sure that you have at least 1.3GB of free space on your SD card
Press A to continue
Press B to return to the main menu
Select "Exit"
Press A to relock write permissions if prompted
Press R+START to power off your console
Insert the console's SD card into your computer
Copy <date>_<serialnumber>_sysnand_00.bin and <date>_<serialnumber>_sysnand_00.bin.sha from /gm9/out to a safe place on your computer, then delete both files from the SD card
Reinsert the SD card into its console
Section III - System Transfer
Perform the system transfer as usual. If you are transferring from a Old 3DS to a New 3DS, choose the option PC-Based Transfer when asked, not Wireless Transfer or Low-Capacity microSD Card Transfer
The prompt mentioning this is not given when transferring between two Old 3DS consoles or two New 3DS consoles. These transfers are almost the same as PC-Based Transfers, but ask you to move the source console's physical SD card to the target console rather than just copy the data over. This part can be ignored without consequence, and you can copy the data between the SD cards anyway
If you have the option to pick a PC-Based Transfer but do not have access to a PC, be aware that during a Wireless Transfer, homebrew software, cartridge dumps, and any other data only obtainable through CFW will not be transferred over. You will need to take extra steps to move over the lost data. If you pick a Wireless Transfer in this case anyway, select "Do Not Delete" when prompted on the target console to preserve all data on the source console's SD card, or else you will have to manually reobtain all lost homebrew/dumps/etc. by hand
Next Steps - Branching of the Way
Were you able to perform a PC-Based Transfer in Section III?
