How to replace the symbols from ARIS 7.1 to ARIS 7.2 in database level without having impact (ie) reports, scripts and existing models

Hi,

I need to replace the existing symbols ie ARIS 7.1 symbols to ARIS 7.2 symbols in database level without having any impact. The existing models,reports, scripts should not get any impact and only the symbols for objects(function,events,it systems,activity,role,document) to be replaced. Can anyone suggest useful information.

Thanks in advance.
