Upgrading the Installation

SSH Tectia Server can be upgraded simply by installing a newer version of the software on top of the older version. On most platforms, there is no need to uninstall the previous version first. The already defined configuration will be preserved untouched.

Exception: On Solaris, the previous version has to be uninstalled before installing a new version.

Before upgrading to a new major or minor release (for example, from 4.1.x to 4.2) remember to update the license file as described in Section Licensing.

Any special considerations are detailed in the platform-specific installation instructions in the following sections.

Note: We recommend that you back up all your configuration files in the /etc/ssh2 directory before starting to upgrade.

Note: Before upgrading, all users must be logged out of the server and the server must be stopped.

Upgrading from SSH Tectia Server (A) to SSH Tectia Server (T)

SSH Tectia Server (A) can be be changed to SSH Tectia Server (T) simply by copying a valid T Server license file to /etc/ssh2/license_ssh2.dat.

SSH Tectia Server (T) can be changed to SSH Tectia Server (A) by copying a valid A Server license file to /etc/ssh2/license_ssh2.dat.

See also Section Licensing.

To take the new license type in use, restart the server as described in Section Starting and Stopping the Server.
