Hardware Do I need the newest firmware for 3DS to 3DS XL data transfer?

[orcid]

I have a 3DS with 5.11 firmware. Because of the gateway I finally want to buy a XL with firmware 4.5.
Can I do the data transfer of all my data and eshop-titles between this two systems without updating the new XL to the newest firmware?
On the Nintendo homepage they say data transfer is with firmware 3.1 and higher possible, but they don`t say if you need the newest firmware for the required internet connection. So I am a little bit confused.

if i am not mistaken, data transfer requires latest system update between 2 systems

Data Transfer is done via the internet and it will update both 3DSes prior to the transfer, so if you want to use the Gateway, you can't transfer.
