It should be possible to reconfigure Cube aggregations/views. For first iteration on Cube dataset we use dataset properties + upgrade procedure to do so.
We cannot support changing of resolutions configured for the Cube: each is stored in its own table while there's no way to dynamically change underlying datasets of the dataset. No support from dataset framework ().
We also cannot force check that resolutions are not changed, at the moment: there's no support for that in dataset framework ().
This issue boils down to verifying that change of aggregations configured for Cube dataset is handled. There seem to be no code needed.
