Cloning is process of creating replica of your source apps 11i Instance ( lets say you have one apps Instance with name VISIONTST and you want to create similar instance ( including same patches & user data) like VISIONPRD then you will use adclone utility (Also called as Rapid Clone these days). In this case source Instance will be VISIONTST and target Instance will be VISIONPRD. There are lot for scenario in which you wish to clone your E-Business Suite 11i Instance , like you want to Test if everything is OK in Test & then after testing want to create Production instance or you want to move your Instance from one machine to other machine or if you are highly experienced Apps DAB you can use clone as staged environment during Upgrade to reduce downtime ( this concept is called as staged appl_top or staged patching/upgrade , p.s. this is different from shared APPL_TOP) So here I am putting broad level steps you will use to clone apps instance .
