Some packages installed on your system have a broken upgrade path from Oracle
Linux version 6 to version 7 (that is, the version of the package is lower in Oracle Linux 7).

This causes a fail of redhat-upgrade-tool run and it might leave the system in an inconsistent state (with mixed Oracle Linux 6 and Oracle Linux 7
packages installed).  Preupgrade scripts make the best effort to force the
redhat-upgrade-tool in-place upgrade process to install packages with broken
upgrade path but you should be aware of that and know what is happening.

Optionally, if possible, remove the packages in question from your Oracle Linux 6 system.
