I would recommend upgrading all the nodes to 1.2.9 as it contains fixes
to known bugs in the versions you are running. Mixing versions is never
recommended mainly because it is hard to test all possible combinations.
It is alright to do so on an interim basis. But never recommended as a
stable setup.
