From SSH Tectia Server for IBM z/OS when Two Versions Exist

If you have SSH Tectia Server for IBM z/OS versions 5.x and 6.x installed on the same machine, you must choose which installation the upgraded system will be based on.

  • To upgrade version 6.0 to 6.1 while keeping the 5.x installation intact, run command:
    ./setup.sh --upgrade-version-6
    
  • When upgrading version 5.x to 6.1, you must choose whether you want to keep the old 5.x version. Choose one of the following upgrade commands:
    ./setup.sh --upgrade-version-5 --keep-old
    
    or
    ./setup.sh --upgrade-version-5 --uninstall-old
    

Note that you cannot have two separate 6.x versions installed on the same machine, so the 6.0 version will be replaced with 6.1 in any case.

The setup script will not restart the server automatically.
