I'm currently using a first generation Pi Model B and have ordered a new Pi 3 Model B+. When it arrives, is it as simple as taking the memory card from the older machine and adding it to the new one?

If not, what else will I need to do to continue with the setup as it is?

(apologies if this is already asked, I've searched and can't find an anwer)

Provided the Pi is running Raspbian Stretch, and you upgrade, the SD will work in all models. The model B (pre B+) used full sized SD Cards; all later models use micro SD Cards.

If you are running an older OS it will not work. Your best bet in this case is a new installation. (SD Cards are cheap enough - use a new card; preferably 16GB, as the newer OS are larger - they will run on a 8GB card, but with little space for new files.)

  • If Stretch was installed with Noobs, I think Noobs needs updating too. – CoderMike Apr 3 '18 at 12:51

As Milliways has pointed out, being able to boot your new Pi from the microSD card in your old Pi will depend upon what version of Raspbian is on that card. I recently upgraded an older model Pi from the wheezy distribution, and it took much more time and effort than creating a new SD card. It's fairly straightforward: download a current image file, "burn" it to a fresh microSD card using Etcher or rufus, make any necessary changes to /boot/config.txt you need, insert the card, apply power and boot.

And the advantage of this approach is that you still have your old Pi to use.

Thanks for the advice everyone, I ended up formatting a new card and installing each service as I needed it, and then copying the config over from the old Pi. About a week later, everything is running fine on the new Pi and I'm trying to think of something to do with the old one.
