There may also be 'configuration' information in /home/yourusername/. If it were me, I would create a separate partition for open SUSE-11.4 (including separate / and /home partitions) and dual boot between Su SE-9.2 Pro and open SUSE-11.4 and gradually migrate over from 9.2 to 11.4. well, i'm sorry to say that there is no _supported_ upgrade path unless it would be to step from 9.2 to 9.3 to 10.0 to 10.1 etc etc etc..
Most distribution vendors usually concentrated on the server side of Linux, where the platform was rapidly becoming adopted.
This document provides guidance and an overview to high level general features and updates for SUSE Linux Enterprise Server 12 SP2.
Besides architecture or product-specific information, it also describes the capabilities and limitations of SUSE Linux Enterprise Server 12 SP2.
the easiest way to get a stable open SUSE system would be to save your data to an off machine location and do a format install of 11.4--careful, if yours is a desktop-less, or headless server you are gonna be (probably) disapointed to learn that open SUSE 11.4 is *not* your daddy's Su SE 9.2 the default install of 11.4 with will be a full-up desktop machine with either KDE, Gnome, LXDE or other GUI....a server install is possible, of course, but you have select that during install...see: 5, to have a full up server you must select "Other" and then . and, you might note that the service life of open SUSE is far shorter (see: than that of the enterprise version SUSE Linux Enterprise Server (see: (from 11.2 x86_64 "Emerald" at Telcontar) :-P But it has to be explained, there are limitations: - It can not be done in one big step.
come to think of it, there _may_ be a smooth easy upgrade path from SUSE Linux 9.2 Professional to SUSE Linux Enterprise Server version 11, check it out at novell.com/linux and in their fora at forums.let us know what your needs are if you intend to use open SUSE.. If I remember correctly, the term "professional" meant the paid DVD vs the downloaded install. - It can not be done "live": that is certainly not supported. - The support is "past tense" for some of the steps.
