1 [[!meta title="Upgrading a Tails USB stick or SD card"]]
3 Tails includes an automatic mechanism to upgrade a USB stick or a SD card to
4 newer versions. When it is not possible to do this **automatic upgrade**, it is
5 possible to do a **manual upgrade**. This page describes both techniques.
9 Our upgrades always fix important security issues so it is important to do them
14 Both techniques only work if the upgraded device, USB stick or SD card, was
15 installed using <span class="application">Tails Installer</span>. **The
16 persistent storage on the device will be preserved.**
20 If you use Tails from a DVD or if your Tails device was not installed using
21 <span class="application">Tails Installer</span>, it is not possible to upgrade
22 and you need to follow our [[installation instructions|download#media]] again
23 with the new ISO image.

31 Automatic upgrade using <span class="application">Tails Upgrader</span>
32 =======================================================================
34 After starting Tails and connecting to Tor, <span class="application">Tails
35 Upgrader</span> automatically checks if upgrades are available and then
36 proposes you to upgrade your device. The upgrades are checked for and downloaded
39 The advantages of this technique are the following:
41 - You only need a single Tails device. The upgrade is done on the fly from a
42 running Tails. After upgrading, you can restart and use the new version.
43 - The upgrade is much smaller to download than a full ISO image.
44 - The upgrade mechanism includes cryptographic verification of the upgrade.
45 You don't have to verify the ISO image yourself anymore.
49 - A Tails device, USB stick or SD card, installed using
50 <span class="application">Tails Installer</span>.
51 - An Internet connection.
53 After connecting to Tor, if an upgrade is available, a dialog box appears and
54 proposes you to upgrade your device.

70 If you decide to do the upgrade, click on <span
71 class="guilabel">Upgrade now</span>,
72 and follow the assistant through the upgrade process.

80 If an error occurs, the assistant proposes you to read one of the following
83 - If an error occurs while checking for available upgrades:<br/>
84 [[file:///usr/share/doc/tails/website/doc/upgrade/error/check.en.html|upgrade/error/check]]
85 - If an error occurs while download the upgrade:<br/>

99 They might also contain <strong>special instructions for upgrading</strong>.
105 If you use Tails from a DVD or if your Tails device was not installed using
106 <span class="application">Tails Installer</span>, it is not possible to upgrade
107 and you need to follow our [[installation instructions|download#media]] again
108 with the new ISO image.
112 It might not always be possible to do an automatic upgrade as described above.
115 - No automatic upgrade is available from our website for this version.
116 - The automatic upgrade is impossible for technical reasons (not enough
117 memory, not enough free space on the device, etc.).
118 - You want to upgrade from another Tails device which already has a newer
119 version installed, for example when working offline.
120 - The automatic upgrade failed and you need to repair a Tails device.
122 In that case, <span class="application">Tails Installer</span> allows you to
123 manually upgrade a USB stick or SD card to a newer version of Tails. Using <span
124 class="application">Tails Installer</span> you can either:
126 - [[Upgrade by cloning from another device|upgrade#clone]] which already
127 runs a newer version of Tails.
128 - [[Upgrade from an ISO image|upgrade#from_iso]] of a newer version of
133 Like for installing, you need to start <span class="application">Tails
134 Installer</span> from another media than the device that you want to upgrade.
