then you must provide the same `-f` flag value to the `istioctl upgrade` command.
{{< /warning >}}
`istioctl upgrade` does not support the `--set` flag. Therefore, if you
installed Istio using the `--set` command, create a configuration file with
the equivalent configuration options and pass it to the `istioctl upgrade`
command using the `-f` flag instead.
If you installed Istio using `--set` flags, ensure that you pass the same `--set` flags to upgrade,
otherwise the customizations done with `--set` will be reverted. For production use, the use of a
configuration file instead of `--set` is recommended.
If you omit the `-f` flag, Istio upgrades using the default profile.
