I tried again on DC;
# cibadmin -R -x update.xml
# cibadmin -S

The whole update.xml is here;
     <resources>
       <group id="grpDummy">
         <primitive id="prmDummyC" class="ocf" type="Dummy"
provider="heartbeat"/>
         <primitive id="prmDummyA" class="ocf" type="Dummy"
provider="heartbeat"/>
         <primitive id="prmDummyB" class="ocf" type="Dummy"
provider="heartbeat"/>
       </group>
     </resources>

The resource order was changed well,
but it seems that they restart.
see the attached logs.

It might be the same issue with this;
