Resolution:
When the up2date command is executed, the new available packages are installed. When required, old packages can be downloaded and installed using the up2date command. Here is an example how to install the old version:

The latest version of the kernel package in use is kernel-2.6.9-34.EL and the architecture is i686. Now, if a user needs to revert back to an older kernel version, for example, kernel-2.6.9-5.EL, the following command can be used:

# up2date --get kernel-2.6.9-5.EL.i686.rpm

Note: The full package name and the architecture of the package is necessary.

The executed command above will download the package version in /var/spool/up2date directory. To install the package, use the rpm command:

# rpm -ivh /var/spool/up2date/kernel-2.6.9-5.EL.i686.rpm
