I hope that we don't need to run this backward migration but this currently would cause some issues. Under the current setup, there are 2 sample concepts. One is viewable(not queryable) and contains sample, project, and batch and one is queryable(not viewable) and contains just contains sample. The reason for this is that there isn't(wasn't?) a way to have fields in a concept but exclude them from queries and keep controls for those fields from appearing on the query page. I really do not think this is a major issue but if we do migrate backwards here, we will need to go in and manually change one of the sample concepts to just be viewable.

An alternate approach to this migration would be to remove the queryable sample concept in the forward migration and create it in the backward migration.
