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.It is rare for a 'yum update' to disturb already working applications. It is possible of course, but the point of 'enterprise' distributions is that a lot of care is taken to not break things (i.e. make changes that aren't backwards compatible) within a major release version. Not sure if it is necessary but there were some quirks in the updates along the way that might make it a good idea to: yum update glibc\* rpm\* yum\* python\* before doing a full 'yum update'.
I might suggest a yum clean all before the above command. I've seen a 5.0 yum update to a 5.6 without issue, but there was very little on the server.
