Updating SUSE Linux
Enterprise
SUSE® Linux Enterprise provides the option of updating an existing system to the new
version without completely reinstalling it. No new installation is needed. Old data, such
as home directories and system configuration, is kept intact. During the life cycle of
the product, you can apply Service Packs to increase system security and correct software
defects. Install from a local CD or DVD drive or from a central network installation
source.
10.1 Updating SUSE Linux Enterprise
Software tends to "grow" from version to version. Therefore, take a look at the available
partition space with df before updating. If you suspect you are running short of disk
space, secure your data before updating and repartition your system. There is no general
rule of thumb regarding how much space each partition should have. Space requirements
depend on your particular partitioning profile and the software selected.
10.1.1 Preparations
Before updating, copy the old configuration files to a separate medium, such as
streamer, removable hard disk, USB stick, or ZIP drive, to secure the data. This primar-
ily applies to files stored in /etc as well as some of the directories and files in /var
and /opt. You may also want to write the user data in /home (the HOME directories)
to a backup medium. Back up this data as root. Only root has read permission for
all local files.
