Hello Group, I am installed some application running on top of Centos 5.2 OS and these applications are running fine. However, we are thinking of upgrading our 5.2 Centos to 5.7 (hot upgrade). That is we want to upgrade from 5.2 Centos to 5.7 Centos and not disturb the applications. Is it possible? Could someone please help. -- Thanks Nagrik
