Live Cache Upgrade from 7.7 to 7.9

Hi Gurus,

I am getting below issue while during upgrade of Live cache from 7.7 to 7.9 version, below is the command I am running from the Upgrade guide

LCUPDATE.BAT -s <SAPSID> –d <liveCache name> -u <DBM,DBM password>

& while running the command on window server I got below error:

ERROR: The usage parameter db_name is not set.

USAGE: LCUPDATE [options]

[options] for the SAP liveCache server upgrade:

        -s       sap_name         (SAP system name)

        -d       db_name          (SAP liveCache name)

        -u       dbm,dbmpasswd    (DBM user authorization)

[options] for the SAP liveCache client upgrade:

        -s       sap_name         (SAP system name)

        -client                   (client software upgrade)

Could you please help on the same. I have already upgraded SCM 7.0 EHP1 to EHP2.
