Several sources can intentionally share a destination

A many-to-one mapping may be valid, but can also hide a lost page or overly broad migration. Check the intended content relationship alongside the graph. Exact mapping analysis cannot predict the behavior of wildcard rules, query rewriting or a server configuration you have not supplied.

It exports reviewed data and does not change a server.
