REDHAT-UPGRADE-TOOL(8)

NAME
redhat-upgrade-tool - Red Hat Upgrade tool

SYNOPSIS

redhat-upgrade-tool [OPTIONS] SOURCE

DESCRIPTION

redhat-upgrade-tool is the Red Hat Upgrade tool.

The redhat-upgrade-tool client runs on the system to be upgraded. It determines what packages are needed for upgrade and gathers them from the source(s) given. It also fetches and sets up the boot images needed to run the upgrade and sets up the system to perform the upgrade at next boot.

The actual upgrade takes place when the system is rebooted, using the boot images set up by redhat-upgrade-tool. The upgrade initrd starts the existing system (mostly) as normal, lets it mount all the local filesystems, then starts the upgrade.

When the upgrade finishes, it reboots the system into the newly-upgraded OS.

OPTIONS

  Optional arguments

-h, --help

  SOURCE

These options tell redhat-upgrade-tool where to look for the packages and boot images needed to run the upgrade. At least one of these options is required.
