I have shapefiles and geodatabases that I want to migrate into a LGIM geodatabase. I have been able to create an empty LGIM with my preferred coordinate system. I have tried to migrate a few feature datasets into the empty LGIM using the "append" tool. Some of the feature points haven't transferred within a dataset, but some have. I also want to bring in fields that a not part of the existing LGIM.
