5 Upgrading NVR System
NVR System is continually developed and enhanced and new releases are published regularly. Also
bug-fix 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
Thecus (see also 1.2 What is new with this release on page 5).
In contrast to an installation from scratch an upgrade preserves all archive image data and also
configuration data (cameras, users, etc.) of your NVR System installation.
We distinguish between a “small upgrades” and a “big upgrades”:
•
A “small upgrade” upgrades the NVR System 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 1.9 to release 3.4, 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.
The following table shows from which upgrades are possible and which upgrades are small or big:
