Hum… the module actually got migrated, to me it looks more like a packaging issue for the community module. It does depend on:
it.geosolutions.imageio-ext imageio-ext-rawbut that library is not included in the base GeoServer so.. @overkamp why don’t you try to download
https://repo.osgeo.org/repository/geo-solutions-cache/it/geosolutions/imageio-ext/imageio-ext-raw/2.0.1/imageio-ext-raw-2.0.1.jar and add it inside the GeoServer WEB-INF/lib?
Does that make the DDG community module work?
Cheers
