This bit is interesting. I dont know anything about 'Parallel' so keep
that in mind.
Most vendors when they say only 1 release and only that specific release
is supported do so because they have kernel modules that are built
against the kernel shipped in that version. Now when you install
CentOS-5.0 you get the kernel that was shipped with 5.0 - when you do
the yum updates, that kernel is not removed. The default policy for yum
on CentOS is to not 'upgrade' the kernel, but to also install a newer
one, if its available. Primary focus of this policy is to address the
specific issue you are running up against, and also in cases where
people have specific hardware support drivers compiled into the kernel
or when they are running custom builds of the kernel.
Now, I dont know what parallel is or what you are doing there, but I
dont belive the Vendor that only one update level is supported. Perhaps
they have a dependancy on a specific package ( like the kernel ) - those
are easy to lock into a version with things like yum-versionlock.

you dont need to reinstall to get from 5.0 to 5.2, if you do a yum
update, that will bring in all the updated packages. ( remember
5.0+updates == 5.2 ).
