In the case of an upgrade installation, as many configuration information as possible is
automatically incorporated from the previous version. Although it is possible to deinstall the
previous version with the option of saving only a part of the data, it is recommended to save
all configuration data.
Before you upgrade Advanced Server for UNIX, it is strongly recommended that
you back up the contents of the /var/opt/lanman directory after the deinstallation.
First a general description of the installation steps is given.
Afterwards, the following installations are described separately:
● Upgrade installation of a primary domain controller from Version 2.x
● Upgrade installation of a backup domain controller from Version 2.x
● Upgrade installation of a primary domain controller from Version 3.5 or 4.0
● Upgrade installation of a backup domain controller from Version 3.5 or 4.0
● New installation of a primary domain controller
● New installation of a backup domain controller
4.8.1.1 Installation steps
Before starting the installation, be prepared to answer the following questions.
Remember you can change your selections after the server installation process is
complete.
Stop the server
You are first asked if you want to stop the server if it is running.
This is for security reasons only, because the installation cannot continue if the server is running.
The installation will abort if the server is running and you do not choose to stop the server.
Because this happens very early during installation, this question is asked every time
regardless of the actual system configuration.
