It is important, that they come all together. The simplest way to ensure this would be to require that the assignments are all included within a single SET command.

The normal approach would be to use a "test and increment" object. You would read the value of this object before you start the configuration, and then include this assignment as part of each SET command. (incrementing the value after each assignment). If another application is trying to manipulate the same set of data, then their SET of this testAndIncrement object will have the wrong value, and hence fail. Note that this does require both management applications to use this mechanism. it doesn't protect against "rogue" updates.
