Change configuration of BPC MS 7.5

Hi,

I am not technical IT savvy person however I need to change the configuration of our current BPC MS 7.5 DEV environment for the OLAP server and DB server. The server is based on cloning image and set up in new environment. However the OLAP and DB server still pointing at MYHQ308 whereas it should be pointing to new server of MYHQ312S (refer to enclosed screensshot). How can I update it to point to new server of MYHQ312S from current MYHQ308S.
