I am about to upgrade a web server from pi2b to pi3b. I would like to know if I can take the SD card as it is from the Pi2b and use It in the pi3b, and the higher performance options for the pi3b be recognized? I really don't want to start a fresh install for the pi3b and transfer the Web site if I don't have to. Distro is raspbian Jessie. Thanks yall

Yes - provided the OS is new enough. You don't say what OS you are using. Assuming Raspbian Jessie you need kernel 4.1.18 or later.

To be on the safe side to a sudo apt-get update followed by sudo apt-get upgrade first.

I would recommend sudo apt-get dist-update which will get the latest, released a few days ago. This has some useful additions, but you will need to install extra packages to get all of these see https://www.raspberrypi.org/blog/#another-update-raspbian

  • thank you. And I edited the post to reflect accurate OS. So far as I know it's got the recent update. – BadgerTrucking May 17 '16 at 23:37
