Migrate hassos from Raspberry 4 to 400

I’d like to migrate my current Hassos from a Raspberry Pi 4 to a 400.
It’s running from SSD with MariaDB, Conbee II.

As the Raspberry Pi 4 and 400 seem to be nearly identical, can I just unplug the SSD and Conbee II from my current Pi and plug them into the Pi 400, run it and just change the Deconz device configuration if necessary? Am I missing something important?

Of course I will do a backup before just to be safe.

I’ve googled a lot but can’t find any information on that topic.
Thanks for your help.
