3.3 Types of HDLM Installation
This section describes the following HDLM installation types: new installation,
upgrade installation, migration, and re-installation.
New installation of HDLM
Installing HDLM on a server where HDLM has not yet been installed is called a
new installation.
Upgrade installation of HDLM
Installing a new version of HDLM over an already installed, earlier version of
HDLM without first uninstalling the earlier version is called an upgrade
installation.
You can perform an upgrade installation only for HDLM version 5.9 or later.
Migration of HDLM
Uninstalling HDLM version 5.8.1 or earlier, and then performing a new
installation of HDLM 5.9 or later is called a migration. During a migration, you
can inherit the earlier ODM settings and the HDLM functionality settings.
Migration is necessary because HDLM version 5.8.1 or earlier cannot be
upgraded to HDLM version 5.9 or later. By performing the procedure described
in 3.5.6 Migrating from HDLM Version 5.8.1 or Earlier to Version 5.9 or Later,
you can inherit only the ODM settings and the HDLM functionality settings.
Re-installation of HDLM
Installing the same version of HDLM for repair purposes without uninstalling the
existing instance of HDLM is called re-installation of HDLM.
