# Upgrading the System
|
|
|
|
The admin-exec command `upgrade` can be used to install software images, or
|
|
bundles. A bundle is a signed and self-contained package that carries all the
|
|
information necessary to determine if it holds a bootloader, a Linux image, or
|
|
even both.
|
|
|
|
To install a new software image to the currently *inactive* partition[^1], we
|
|
use the `upgrade` command and a URI to a ftp/tftp/sftp or http/https server
|
|
that hosts the file:
|
|
|
|
```
|
|
admin@example:/> upgrade tftp://192.168.122.1/firmware-x86_64-v23.11.pkg

The secondary partition (`rootfs.1`) has now been upgraded and will be used as
|
|
the *active* partition on the next boot. Leaving the primary partition, with
|
|
the version we are currently running, intact in case of trouble.
|
|
|
|
See [Upgrade & Boot Order](../upgrade.md) for more information on upgrading.
|
|
|
|
[^1]: It is not possible to upgrade the partition we booted from. Thankfully
|
|
the underlying "rauc" subsystem keeps track of this. Hence, to upgrade
|
|
both partitions you must reboot to the new version (to verify it works)
|
|
and then repeat the same command.
