In many cases, you have to move a dimension value Id mapping file between environments (i.e. staging, production, fail over, and so on). You can coordinate this work in your Deployment Template script by calling exportDimensionValueIdMappings() on the ContentAcquisitionServerComponent, copying the file to the necessary machine, and calling importDimensionValueIdMappings() to load the file into another instance of a Dimension Value Id Manager.
