I have configured by raspberry pi as a wifi access point using a 32GB SD card, and installed postgres. I would like to clone the SD card (from my mac) to smaller size SD cards (like 16GB, or potentially 8GB cards). Is this possible (knowing that I use mush less than 8GB space on the card)?
Is there something more to do than just usual dd commands?
I tried with an 8GB card, but it didn't work, although I got no error message.
