I have set-up a rPi 3 installed and configured some software on it.
I now want to use this set-up on a rPi3B+ with a SSD.
I have checked that the 3B+ accepts the SSD by using Etcher to put Stretch on the SSD, and connecting the SSD to the rPi3B+ and it boots of it.
I now want to copy the SD card to the SSD, and was wondering how best to achieve this.
a) can I use Etcher to make an image of the SD card and then write it onto the SSD?
b) stick the SD card into the rPi3B+ and copy the contents to the SSD, thus overwriting the new image I just booted from?
c) redo the work I did on the SD card and the rPi3, by reinstalling all software onto the new hardware.
Any hints appreciated.
