Nextcloud Box with Raspberry Pi 4 (4gb)

Hi, I have a nextcloud box which I would like to upgrade to raspberry pi 4. I read that it supports raspberry pi 2 and 3. My question is if its theoretically possible or not… ( power supply etc… )
Thanks in advance.

I have the same question. @Seferi what did you end up doing?
