Does anyone have a document that explains in detail the why and how of the pre-migration utilities? I know vaguely that it compares detail records to summary and where there's a discrepancy there is an entry made. But I know this customer is going to dig for more detail.
IT person started on the path to their own upgrade and ran pre-migration which they then ""ok'd"" to post not realizing that it would impact live data. Oops.
