OVS 1.7 was released in July 2012, so by the time current OVS is released, it will be almost four years old. I think that this is long enough to remove special upgrade code. It's almost impossible to do this upgrade in any case since there is no overlap in the base kernel versions supported by the out of tree modules in the two versions (the only possibility is running the new version of OVS on the upstream module from Linux 3.3).
