 Before upgrading check if any special steps are required to upgrade from the

 instructions that may be required are listed later in this document.

+To check whether your update was successful, you can check the running server
+version with:
 
 .. code:: bash
 
-    # replace <host.name> with the hostname of your synapse homeserver.
-    # You may need to specify a port (eg, :8448) if your server is not
-    # configured on port 443.
-    curl -kv https://<host.name>/_matrix/client/versions 2>&1 | grep "Server:"

+Rolling back to older versions
+------------------------------
+
+Rolling back to previous releases can be difficult, due to database schema
+changes between releases. Where we have been able to test the rollback process,
+this will be noted below.
+
+In general, you will need to undo any changes made during the upgrade process,
+for example:
+
+* pip:
+
+  .. code:: bash
+
+     source env/bin/activate
+     # replace `1.3.0` accordingly:
+     pip install matrix-synapse==1.3.0
+
+* Debian:
+
+  .. code:: bash
+
+     # replace `1.3.0` and `stretch` accordingly:
+     wget https://packages.matrix.org/debian/pool/main/m/matrix-synapse-py3/matrix-synapse-py3_1.3.0+stretch1_amd64.deb
+     dpkg -i matrix-synapse-py3_1.3.0+stretch1_amd64.deb
