The following additional installation options are supported:
Installations are based on default installation images. However, you can build a custom image based on any of the default images. The distribution constructor tool enables you to specify parameters for building a new image. See Creating a Custom Oracle Solaris 11.4 Image.
Through the Unified Archives feature, you can clone an existing Oracle Solaris system and use that image as a basis for the installation. See Using Unified Archives for System Recovery and Cloning in Oracle Solaris 11.4.
You cannot use the installer tool to update existing Oracle Solaris systems. Instead, you use the pkg utility to access package repositories and download new or updated software packages for your system. For further information, see Updating Your Operating System to Oracle Solaris 11.4 and Updating Systems and Adding Software in Oracle Solaris 11.4.
