NETAVIS Observer 4.6 Server Installation and Administration (October 2015)
5 Upgrading Observer
Observer is continually developed and enhanced and new releases are published regularly. Also bugfix releases are published. Therefore it might be possible that you want to upgrade to a newer release
than the one actually installed.
First make sure that you want to upgrade to the new release by reading the Release Notes of the new
release. You can find the release notes either on the installation DVD-ROM or on the homepage of
NETAVIS (see also 1.2 What is new with this release on page 6).
In contrast to an installation from scratch an upgrade preserves all archive image data and also
configuration data (cameras, users, etc.) of your Observer installation.
We distinguish between a “small upgrades” and a “big upgrades”:
 A “small upgrade” upgrades the Observer application code and related programs but does
not upgrade/replace the underlying operating system or system components. For example, an
upgrade from 1.8.0 to 1.8.2 is a small upgrade.
A small upgrade can be executed from various upgrade sources like network resource, http or
DVD-ROM drive and can also be done via secure shell from a remote machine.
 A “big upgrade” upgrades everything, also the underlying operating system. Upgrading from
release 4.0 to release 4.6, for example, is a big upgrade.
A big upgrade can only be executed from the server console and a DVD-ROM drive needs to be
connected directly to the server.
If you are updating from a previous version of NETAVIS Observer or are running an unbundled system
then please note that Observer 4.6 requires at least CentOS / RHEL 6.2 to work. This means that from
Observer 4.4 and Observer 4.5 systems (using the bundled CentOS 6.2 or 6.4) a small update is
sufficient to get Observer 4.6. For all other Observer systems a big update is required. If you have any
doubts about which update is needed for your system then please get in touch with our support team.
Refer to the table below for an overview of the possible update methods depending on your Observer
