How to do an in-place upgrade to the latest openSUSE Leap release

A major advantage of doing an in-place upgrade compared to doing a clean install, is that all accounts, configurations, and installed programs are kept intact. Using Windows Subsystem for Linux (WSL) , I have installed a fresh instance of openSUSE 42. 1 ### *How can I perform an in-place upgrade of openSUSE 42 to 15.x?* My primary interest is in going from openSUSE 42 to the latest openSUSE version. At the time of writing, Leap 15.4 is the latest active openSUSE release . #### Motivation WSL still offers only version 42.2 of openSUSE when installing from the command line. Considering that the lifetime of openSUSE 42.2 officially ended in January 2018 – almost five years ago – it would make sense to upgrade to a newer version. #### Caution! *Make sure there is enough free disk space before considering an in-place upgrade, in this case, at least about 5 GiB.* ## References * How to install Linux on Windows with WSL * Active openSUSE Leap releases * openSUSE Leap discontinued distributions --- 1 Open [Windows CMD.exe](https://ss64.com/nt/cmd.html) as administrator (WinKey+r, type cmd, hold down Ctrl+Shift, press Enter).
