+Upgrade from 2.11.0 to 2.11.1
+=============================
+
+Preparing for the Ubuntu 24.04 (Noble) migration
+------------------------------------------------
+
+The 2.11.1 release includes a number of features that will help ensure
+your SecureDrop server is prepared for the automated migration to Ubuntu 24.04
+(Noble) in early 2025.
+
+SecureDrop 2.11.1 will automatically run checks to ensure all servers are ready for migration to Ubuntu 24.04 (Noble). If issues are found, a banner will be displayed in the Journalist Interface to both admins and journalists. Administrators are encouraged to review the
+:doc:`Ubuntu 24.04 (Noble) migration guide <../admin/maintenance/noble_migration_prep>`
+explaining how to resolve any errors and perform any necessary steps before
+Jan. 31st, 2025.
+
+We will have more details on the migration itself early next year.
+
+Update Servers to SecureDrop 2.11.1
+------------------------------------
+
+Servers running Ubuntu 20.04 will be updated to the latest version of SecureDrop
+automatically within 24 hours of the release.
+
+Update Workstations to SecureDrop 2.11.1
+----------------------------------------
+
+.. important:: We recommend backing up your workstations prior to
+  any upgrades. See our :ref:`backup instructions <backup_workstations>`
+  for more information.
+
+Update to SecureDrop 2.11.1 using the graphical updater
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+On the next boot of your SecureDrop *Journalist* and *Admin Workstations*,
+the *SecureDrop Workstation Updater* will alert you to workstation updates. You
+must have `configured an administrator password <https://tails.net/doc/first_steps/welcome_screen/administration_password/>`_
+on the Tails welcome screen in order to use the graphical updater.
+
+Perform the update to 2.11.1 by clicking "Update Now":
+
+.. image:: ../images/securedrop-updater.png
+
+Fallback: Perform a manual update
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+If the graphical updater fails and you want to perform a manual update instead,
+first delete the graphical updater's temporary flag file, if it exists (the
+``.`` before ``securedrop`` is not a typo): ::
+
+  rm ~/Persistent/.securedrop/securedrop_update.flag
+
+This will prevent the graphical updater from attempting to re-apply the failed
+update and has no bearing on future updates. You can now perform a manual
+update by running the following commands: ::
+
+  cd ~/Persistent/securedrop
+  git fetch --tags
+  gpg --keyserver hkps://keys.openpgp.org --recv-key \
+   "2359 E653 8C06 13E6 5295 5E6C 188E DD3B 7B22 E6A3"
+  git tag -v 2.11.1
+
+The output should include the following two lines: ::
+
+    gpg:                using RSA key 2359E6538C0613E652955E6C188EDD3B7B22E6A3
+    gpg: Good signature from "SecureDrop Release Signing Key <[email protected]>" [unknown]
+
+
+Please verify that each character of the fingerprint above matches what is
+on the screen of your workstation. A warning that the key is not certified
+is normal and expected. If the output includes the lines above, you can check
+out the new release: ::
+
+    git checkout 2.11.1
+
+.. important:: If you do see the warning "refname '2.11.1' is ambiguous" in the
+  output, we recommend that you contact us immediately at [email protected]
+  (`GPG encrypted <https://securedrop.org/sites/default/files/fpf-email.asc>`__).
+
+Finally, run the following commands: ::
+
+  sudo apt update
+  ./securedrop-admin setup
+  ./securedrop-admin tailsconfig
+
