Now referesh the repositories.
server:~ # zypper ref
It is strongly recommended to run upgrade inside GNU screen or tmux to protect the upgrade process in case anything should go wrong with the X session during the upgrade. tmux and screen are available in the main openSUSE repositories.
Here i am using tmux, if you don’t have tmux. Install tmux by using the following command.
server:~ # zypper install tmux
Switch from terminal to tmux.
server:~ # tmux
Enter the following command to start upgrading to openSUSE 13.2.
server:~ # zypper dup
Once the upgrade process is completed, reboot the machine. Check the current OS version.
server:~ # cat /etc/os-release
Output will look like below
NAME=openSUSE VERSION="13.2 (Harlequin)" VERSION_ID="13.2" PRETTY_NAME="openSUSE 13.2 (Harlequin) (x86_64)" ID=opensuse ANSI_COLOR="0;32" CPE_NAME="cpe:/o:opensuse:opensuse:13.2" BUG_REPORT_URL="https://bugs.opensuse.org" HOME_URL="https://opensuse.org/" ID_LIKE="suse"
It’s been confirmed that the machine is upgraded to openSUSE 13.2
What to do after upgrade?
Search for openSUSE 13.2 compatible third-party repositories that you used before, if you still need them; add them using following command.
server:~ # zypper addrepo --name
That’s All. Your machine has successfully upgraded to openSUSE 13.2.
