3. Creating an HDLM Environment

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.
