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 removing 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
Removing 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 Migrating from HDLM Version 5.8.1 or Earlier to Version 5.9
or Later on page 3-53 , 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 removing
the existing instance of HDLM is called re-installation of HDLM.
