    From the SAP support and best practices point of view you need to do a system copy to move the instance to the new machine. Having said that I have moved instances from machine A to machine B by copying the SAP and Oracle filesystems without doing the installation. It works well if you know how to do it without a miss. You also need to make sure that the ownership and permissions are correct after the move. Additionally a new license should be installed.

    • >>If had to move each instances seperatly, do I have to install ASCS for each time?<<

      You need to setup/install ASCS only when you are moving it from one host to another. You don't need to install it multiple times. After the move of database to the new host, just run sapinst and select the ASCS service to install it. For PAS (primary application server) and AAS (additional application servers) you do the same using sapinst on the host where you want them to run. The instructions are there in the guide.
