Solution Verified - Updated -

Environment

  • Red Hat Enterprise Linux all Version.

Issue

  • Is there any supported method to downgrade Red Hat Enterprise Linux Operating System (OS)?

Resolution

  • Red Hat does not support this kind of minor version Operating System downgrade.
  • The recommended method is to take backup of important data and configuration files and then re-install the machine using a Red Hat Enterprise Linux (RHEL) ISO for the required version.

Root Cause

  • Downgrading a system to minor version (ex: RHEL6.1 to RHEL6.0) is not recommended as this might leave the system in broken state where libgcc and other libraries won't rollback as expected.
