   ## systemd Enablement
 
   For all distributions that support systemd (Debian Jessie 8.x,
-  Ubuntu >= 16.04), Ceph daemons are now managed using native systemd
-  files instead of the legacy sysvinit scripts.  For example:
+  Ubuntu >= 16.04), Ceph daemons are now managed using upstream provided
+  systemd files instead of the legacy sysvinit scripts or distro provided
+  systemd files.  For example:
 
     systemctl start ceph.target       # start all daemons
     systemctl status ceph-osd at 12      # check status of osd.12
 
-  The main notable distro that is *not* yet using systemd is Ubuntu 14.04
+  To upgrade existing deployments that use the older systemd service
+  configurations (Ubuntu >= 15.04, Debian >= Jessie), you need to switch
+  to using the new ceph-mon@ service:
+
+    systemctl stop ceph-mon
+    systemctl disable ceph-mon
+
+    systemctl start ceph-mon@`hostname`
+    systemctl enable ceph-mon@`hostname`
+
+  and also enable the ceph target post upgrade:
+
+    systemctl enable ceph.target
+
+  The main notable distro that is *not* using systemd is Ubuntu 14.04
   (The next Ubuntu LTS, 16.04, will use systemd instead of upstart).
