Hi everybody,
Now that the shortage seems to be finally over, I’m planning to upgrade either to a Raspberry Pi 4 with 4 or 8GB. I’m currently using a 4 with only 2GB of memory. Alternatively, I may get a Raspberry Pi 5.
Can I simply put the SD-card with my current dietpi installation in the new one or do I have to set it up from scratch?
Have a nice weekend!
at least just replacing the 4 2GB with a 4 8GB should not be an issue. For the RPI5, we would need to test as soon as we have some samples. Right now, we simply don’t know. 
Upgrading to a larger RAM system as long as it’s the same RPi4B platform 2Gig to 4Gig to 8 Gig will be a non issue (it’s like just slapping more RAM into a regular computer…nothing changed just MORE RAM )…going from a RPi4B to a 5…problem as the processor and peripherals are different
