The product structure and the installation directory of Tectia Server for IBM z/OS has changed in version 6.0. If you have an earlier version of Tectia Server for IBM z/OS installed, it can coexist with version 6.0, as can the 5.x version.
The upgrade procedure will migrate your 5.x configuration and the keys automatically to the 6.x version.
Before proceeding with the installation as described in Installing the Tectia Server for IBM z/OS Software, condsider the following issues.
When you run
setup.sh for upgrading from version 5.x you must choose if you want to keep the old 5.x installation intact or if you want to uninstall all 5.x files. You must run
setup.sh either with

setup.sh script. In case you want to have both the 5.x and the 6.x servers running simultaneously, you must change the TCP port of either one of them, because otherwise the two installed servers will compete for default port 22.

hostkey hostkey.pub sshd2_config ssh_certd_config ssh_ftadv_config random_seed ssh_banner_message ssh-socks-proxy-config.xml upgrade_history auth/ hostkeys/ subconfig/ knownhosts/
If you are using the SOCKS proxy functionality, you must review and update your
ssh-socks-proxy-config.xml configuration file after
setup.sh has finished.
