This question already has an answer here:
I have an RPi 2 B+, which had previously wheezy installed on it. I used the following articles to upgrade to jessie:
It has been successfully updated to jessie, and works without problem.
Now I have bought an RPi 3. I want to take the microSD card from my RPi 2 B+, and insert it to RPi 3.
Is it OK!? Will it work?
Is there anything to do before or after inserting the microSD card into RPi 3!?
