On Solaris platforms, earlier versions of SSH Tectia Server should be removed before installing SSH Tectia Server 5.x. (When installing via SSH Tectia Manager, this is handled automatically.)

On other platforms, SSH Tectia Server can be upgraded from a previous 5.x installation to a later 5.x simply by installing the newer version of the software on top of the older version.

If installed on the same machine, SSH Tectia Client and SSH Tectia Server 5.x should always be upgraded at the same time, because there are dependencies between the common components.

	Note
	Back up all your configuration files before starting the upgrade.
