+How can I change volume type (garr-ct1 and garr-pa1 regions) 
+----------------------------------------------------------
+
+It is possible to change the type of existing volumes, e.g. from **default** to **fast** (based on SSD) type.
+
+To do so, first of all the volume must be detached and must not have snapshots (therefore it is not possible to change the type of system volumes).
+
+From the dashboard select the volume and from the scroll-down menu select "Change Volume Type". 
+N.B. don't forget to choose "Migration Policy: On Demand!"
+
+With the OpenStack CLI the volume retype command is::
+
+    openstack volume set --type <new_type> --retype-policy on-demand <volume-id>

 I need to migrate an instance from a region to another one
