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'.
