1 Introduction

SUSE® Linux Enterprise Micro allows upgrading from an existing system to the new version. No new installation is needed. Existing data, such as home and data directories and system configuration, is kept intact.

Upgrades between two releases of SUSE Linux Enterprise Micro are supported by SUSE. Whether it is better to upgrade or perform a fresh installation depends on your specific scenario. While upgrades involve less work, fresh installations ensure you benefit from all the new features of a release such as disk layout changes, specific filesystem features, and other improvements. To get the most out of your system, SUSE therefore recommends fresh installations in most scenarios.

In both cases—upgrade as well as a fresh installation—customers need to check if system settings and default values still fit their requirements.
