REDHAT-UPGRADE-TOOL(8) redhat-upgrade-tool User Manual 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
Show a help message and exit.
-v, --verbose
Print more info.
-d, --debug
Print lots of debugging info.
--debuglog DEBUGLOG
Write debugging output to the given file. Defaults to /var/log/redhat-upgrade-tool.log.
--reboot
Automatically reboot to start the upgrade when ready.
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
