I have centOS5.3 installed in the system. I have never updated it but now am planning to update. While doing "yum update", is there any possibility that the update might hamper the execution of any software/application installed on the system? Is there anything particular to note before updating the system?

I haven't had any problems in updating CentOS 5.3 to 5.4 or even 5.5 directly. Although I normally use yum upgrade instead of yum update, but the process would probably be the same for both "yum update" and "yum upgrade" in this case.

Just for completeness sake - 'upgrade' has been deprecated for a few years now.

One of the core focus for CentOS platform is to not break stuff for people - in this case you got a free win by the fact that the command still exists ( mostly as an alias ), so your scripts don't break. So the scripts you wrote way back when, continue to work without any user interface breakage.

From the man page:
upgrade Is the same as the update command with the --obsoletes flag set.

I think: yum clean all && yum update glibc* yum clean all && yum update yum* rpm* python* yum update"
And watch out for the .rpmsave or .rpmnew files...

If you are not updating your machine on a regular basis, there will always be a long list of updates when you come around to running them. So make sure you check what repositories you have enabled, what packages are coming from where and what your upgrade process is going to be. Usually, doing a 'yum list updates' will tell you whats going to update - so study that list, and see if anything in there has an impact on your apps and how.
basically : make sure you know whats going to change, and where that change is going to come from.
if everything on your machine did not come from rpms / yum-repos : you might need to workout a plan to upgrade those components as well ( and maybe switch to using rpms for those )
