- *Recommended*: [Install a fresh template to replace an existing one.](https://www.qubes-os.org/doc/templates/fedora/#installing) *This option may be simpler for less experienced users.* After you install the new template, redo all desired template modifications and [switch everything that was set to the old template to the new template](https://www.qubes-os.org/doc/templates/#switching). You may want to write down the modifications you make to your templates so that you remember what to redo on each fresh install. To see a log of package manager actions, open a terminal in the old Fedora template and use the `dnf history` command.
- *Advanced*: [Perform an in-place upgrade of an existing Fedora template.](https://www.qubes-os.org/doc/templates/fedora/in-place-upgrade/) This option will preserve any modifications you've made to the template, *but it may be more complicated for less experienced users.*
