Moving DietPi aarm64 from RPi3 to RPi4

Hello,

Just would like to know whether moving an SDcard with DietPi aarm64 from a Raspberry Pi 3 B+ to a brand new Raspberry Pi 4 is ok, or whether any action must be taken in advance, or a brand new install is mandatory (hopefully not).

Thank you in advance

Moving SD card should be all you need to do.
