Moving Freedombox from Rasspberry Pi 3B+ to Rasspberry Pi 4

Hello everyone.
After a long time of finding out about Freedombox I finally found the time to give it a try.
I made the initial setup on a Raspberry Pi 3B+ but since I also have a rpi4 I was wondering…
Can I just swap the SD-card from one device to the other, together with the external drives? Would it work to the maximum?
What’s your opinion?

Thanks!

Should work. You might as well copy the SD-Card to a usb3 stick and make the Pi4 bootable from usb, if it is not allready.

Thanks for the answer @hanstux and also for the idea of copying the SD-Card to a usb3 hadn’t thought of that.

Just let us know, if it worked!

Ok as soon as I finish setting up the freedombox on my rpi3 I will then test it on the rpi4 and I will let you know.
