You should be looking for objects that are not expected to exist anymore, and objects of buckets that don't exist anymore. The problem here is to identify these. I suggest starting by looking at all the existing buckets, compose a list of all the bucket prefixes for the existing buckets, and try to look whether there are objects that have different prefixes.
