This tutorial is to help you upgrade your current Raspbian OS to the latest version – Buster released in June 2019. For Raspbian OS comparison and Version History please refer to Wikipedia link here. This OS version is backwards compatible to all Raspberry Pi’s. For Pi users, as always there is no major UI changes but a good bit under-the-hood changes and improved security to make it harder to hack.
As with every major version changes in the Debain based Raspbian, the developers recommend to always have a fresh installation over upgrades to ensure you will not be carrying over any issues from previous mods. In order to do so, please visit https://www.raspberrypi.org/downloads/ and download the latest version.
