Upgrade Raspberry Pi to RPi 3

Sometimes it is necessary to exchange an old Raspberry Pi for a new one. I had to do this because my old Raspberry Pi (a very old model B) with its 700 MHz was getting too slow. I switched to the latest model, a Raspberry Pi 3 B, which works much faster with its quad core.

The replacement was surprisingly easy. First we bring the system up to date:

sudo apt-get update

sudo apt-get upgrade

Now we are carrying out a firmware update:

sudo rpi-update

In my case, rpi-update was not yet installed, but this can easily be done:

sudo apt-get install rpi-update

Now we insert the SD card into the new Raspberry Pi and start it. The system now starts with the new Raspberry Pi.
