## Switching

When you install a new template or
[upgrade](/doc/how-to-update/#upgrading-to-avoid-eol) a template, it is
recommended that you switch everything that was using the old template to the
new template:
1. Make the new template the default template.
1. **Make the new template the default template.** In the App Menu, go
to Qubes Tools, then click on Qubes Global Settings. In the Qube Defaults
section, next to Template, select the new template from the
drop-down list. Press OK.
```
Applications Menu -> System Tools -> Qubes Global Settings -> Default template
```
2. **Base your [disposable templates](/doc/glossary/#disposable-template) on
the new template.**
2. If your keyboard or mouse is connected through `sys-usb`, switch `sys-usb`
to the new template. (Note that this is a single command to ensure that
`sys-usb` restarts. If it does not, you will not be able to use your USB
keyboard or mouse.)
- If your only keyboard and mouse are *not* connected through a [USB
qube](/doc/usb-qubes/), or that USB qube is *not* a disposable, then shut
down all disposables. In the App Menu, go to Qubes Tools, then click on
Qube Manager. In the Qube Manager, find your disposable template(s). (By
default, they end in `-dvm`.) Right click, hover over Template, then click
on the new template. Repeat for each disposable template.
```
[user@dom0 ~]$ qvm-shutdown --wait sys-usb; qvm-prefs sys-usb template <NEW_TEMPLATE>; qvm-start sys-usb
```
- If your only keyboard or mouse *are* connected through a USB qube, and
that USB qube *is* a disposable, then you will have to enter a special
command that shuts down all of your qubes, switches the USB qube's
disposable template to the new template, then starts the USB qube again.
In order to avoid being locked out of your system, you must be very
careful to enter this command without typos and with the correct
substitutions.
3. Base app qubes on the new template.
In the App Menu, click on Terminal Emulator. Type the command below,
substituting `<SYS_USB_DISPOSABLE_TEMPLATE>` with the name of the
disposable template on which `sys-usb` is based, `<NEW_TEMPLATE>` with the
name of the new template, and `<USB_QUBE>` with the name of your USB qube.
Other than these substitutions, make sure to enter the command exactly as
written.
```
Applications Menu -> System Tools -> Qubes Template Manager
```
```
qvm-shutdown --wait --all; qvm-prefs <SYS_USB_DISPOSABLE_TEMPLATE> template <NEW_TEMPLATE>; qvm-start <USB_QUBE>
```
4. Base the [disposable template](/doc/glossary/#disposable-template) on the new
template.
With substitutions, your command should look similar to this example.
(Warning: This is just an example. Do not attempt to use it.)
```
[user@dom0 ~]$ qvm-create -l red -t <NEW_TEMPLATE> <NEW_DISPOSABLE_TEMPLATE>
[user@dom0 ~]$ qvm-prefs <NEW_DISPOSABLE_TEMPLATE> template_for_dispvms True
[user@dom0 ~]$ qvm-features <NEW_DISPOSABLE_TEMPLATE> appmenus-dispvm 1
[user@dom0 ~]$ qubes-prefs default-dispvm <NEW_DISPOSABLE_TEMPLATE>
```
```
qvm-shutdown --wait --all; qvm-prefs fedora-01-dvm template fedora-02; qvm-start sys-usb
```
3. **Base your app qubes on the new template.** In the Qube Manager, click on
the Template heading to sort by template. Select all the qubes based on the
old template by clicking on the first one, holding shift, then clicking on
the last one. With multiple qubes selected, right-click on any of them,
hover your cursor over Template, then click on the new template.
