An update installation refers to upgrading HDLM whose version is 5.9
or later. Therefore, it does not include a migration from HDLM version
5.8.1 or earlier to HDLM version 5.9 or later. It also does not include a
migration from HDLM version 5.9 or later to HDLM version 5.8.1 or
earlier. For such installations, you must first remove the existing
HDLM and then install HDLM version 5.9 or later. To migrate from
HDLM version 5.8.1 or earlier to HDLM version 5.9 or later, you can
use the dlmmigsts utility for assisting HDLM transitions to inherit the
existing HDLM settings. For details, see Migrating from HDLM Version
5.8.1 or Earlier to Version 5.9 or Later on page 3-53 .
