Operation Manual
You also have the possibility to make backups of various system components.
Selecting backups slows down the upgrade process. Use this option if you do
not have a recent system backup.

Conrm the upgrade by clicking Start Update.
Once the basic upgrade installation is nished, YaST reboots the system. Finally, YaST
updates the remaining software, if any and displays the release notes, if wanted.
14.1.4 Distribution Upgrade with zypper
With the zypper command line utility you can upgrade to the next version of your
distribution. Most importantly, you can initiate the system upgrade process from within
the running system.
This feature is attractive for advanced users who want to run remote upgrades or up-
grades on many similarly congured systems. Inexperienced users will prefer the upgrade
with YaST using a boot medium as described in Section 14.1.3, “Upgrading with YaST”
(page 215).
Before Starting the Upgrade with zypper
To avoid unexpected errors during the upgrade process using zypper, minimize risky
constellations.
Upgrade from the previous version (e.g., 11.2) to this version (11.3)—do not skip any
minor version inbetween (this means, do not upgrade from 11.1 or earlier to 11.3 in
one go). Make sure all available 11.1 online updates are successfully applied.
Close as many applications and unneeded services as possible and log out all regular
users.
Disable third party or openSUSE Build Service repositories before starting the upgrade,
or lower the priority of these repositories to make sure packages from the default system
repositories will get preference. Enable them again after the upgrade and edit their
version string to match the version number of the distribution of the upgraded now
running system.
