+   **NOTE**: Before live patching Virtual Routers (VRs), administrators must ensure that
+   the global configuration parameter ``minreq.sysvmtemplate.version`` is set
+   to the minimum supported VR template version.
+
+   For example, if the deployed Virtual Router template version is ``4.20.1``,
+   set:
+
+   ::
+
+      minreq.sysvmtemplate.version = 4.20.1
+
+   This ensures that live patching is only performed on Virtual Routers running
+   template version ``4.20.1`` or later. Virtual Routers using older template
+   versions must be upgraded before live patching is attempted.
 
    With respect to VRs, a Network restart without cleanup is initiated to during live patching to ensure all rules
    are re-applied.
