+
+   Starting in version 1.11.0, ``mongosync`` does not support live upgrades. To
+   upgrade to the most recent version, see :ref:`c2c-release-version-numbers`. 
+
+
+Starting in ``mongosync`` 1.7.0, you can live upgrade ``mongosync`` without
+restarting data synchronization operations from the beginning.
+
+After the live upgrade, ``mongosync`` continues operations that were in
+progress before the upgrade.
+
+To live upgrade ``mongosync``, perform these steps:
+
+.. procedure::
+   :style: normal
+
+   .. step:: (Optional) Pause the ``mongosync`` processes
+
+      To pause ``mongosync``, run :ref:`c2c-api-pause` on each running
+      ``mongosync`` process.
+
+      You can resume the ``mongosync`` processes later from the paused
+      state, as shown in the final step.
+
+      .. tip::
+
+         If you don't want to immediately resume data synchronization
+         operations after live upgrade, consider pausing the
+         ``mongosync`` processes. This is useful if you're coordinating
+         operations from multiple ``mongosync`` processes.
+
+   .. step:: Stop the ``mongosync`` processes
+
+      Use your operating system to stop each running ``mongosync``
+      process. To stop a process, see your operating system
+      documentation for the specific steps.
+
+   .. step:: Download and install the new ``mongosync`` binaries
+
+      To download and install the new ``mongosync`` binaries, see
+      :ref:`download and install mongosync <c2c-install>`.
+
+   .. step:: Initialize the ``mongosync`` processes
+
+      To initialize the ``mongosync`` processes, see 
+      :ref:`Quickstart <c2c-quickstart>`. During initialization after a
+      live upgrade, ``mongosync`` updates the persistent metadata.
+
+   .. step:: Resume the ``mongosync`` processes
+
+      If you paused any ``mongosync`` processes earlier in the optional
+      first step, run :ref:`c2c-api-resume` on all ``mongosync``
+      processes.
+
+If a data synchronization operation was already in progress before the
+live upgrade, new features added in the latest ``mongosync`` version may
+not all be supported after the live upgrade. Performance improvements
+and bug fixes are always supported after the live upgrade. For more
+information on the new features that might be supported after a live
+upgrade, see the :ref:`1.7.0-c2c-release-notes`.
