.SH NAME
dnf5-system-upgrade \- System-Upgrade Command
.SH SYNOPSIS
.sp
\fBdnf5 system\-upgrade <subcommand> [options]\fP
.SH DESCRIPTION
.sp
The \fBsystem\-upgrade\fP command is used to upgrade the system to a new major release. First, the \fBdownload\fP subcommand downloads packages while the system is running normally. Then, the \fBreboot\fP subcommand reboots the system into a minimal \(dqoffline\(dq environment to apply the upgrades.
.sp
\fBdnf5 system\-upgrade\fP is a recommended way to upgrade a system to a new major release. Before you proceed, ensure that your system is fully upgraded (\fBdnf5 \-\-refresh upgrade\fP).
.sp
\fBsystem\-upgrade\fP shares many subcommands with the \fI\%offline subcommand\fP\&.
