How to Upgrade your openSUSE 12.2 Install to KDE 4.10
Caveat: *As with any upgrade there are risks. openSUSE 12.2 has a perfectly usable version of KDE. This upgrade requires a vendor or package switch to a non standard repository (it is though considered stable and safe) and as such it requires user intervention, such intervention will differ due to factors beyond the control of the author of this guide. This basically means, YOU are responsible for your system and the choices you make. If you are at any time unsure about a choice required during the upgrade, we suggest you make a note and ask for help before proceeding. It is recommended that any upgrade take place on a fully patched/updated system. If you have been using KDE49, you will need to remove/disable these repos before adding the new ones for KDE410 and proceeding with this upgrade.
