Chapter 37. Upgrading Your Current System

The procedure for performing an in-place upgrade on your current system is handled by the following utilities:
  • The Preupgrade Assistant, which is a diagnostics utility that assesses your current system and identifies potential problems you might encounter during and/or after the upgrade.
  • The Red Hat Upgrade Tool utility, which is used to upgrade a system from Red Hat Enterprise Linux to version 7.
The current documentation for testing this procedure can be found in the following Red Hat Knowledgebase article: https://access.redhat.com/site/solutions/637583
