ArcPy replaceDataSource to ArcSDE raster catalog error?

Question

I'm trying to re-path a multitude of rasters currently the workspace is a folder, the intended workspace is a raster catalog in an SDE database - using the replaceDataSource method I'm getting the error as below. Does anyone know if this method can't output as a Raster Catalog or what the actual problem may be?

lyr = arcpy.mapping.Layer(r"C:\Folder\MyLayer.lyr")
lyr.replaceDataSource(r"pathToSDEConnectionFile.sde","SDE_WORKSPACE","rasterCatalogName", True)

Runtime error : Layer: Unexpected error

Answer 1

The second argument is the type of the new dataset. I don't think a raster catalog is an sde workspace even if stored in sde; only sde connections are. Try using "RASTER_WORKSPACE" for your keyword.
