Mastership restrictions prevent most inconsistent changes in different replicas, but some are unavoidable.

When naming conflicts occur, MultiSite displays the name of the originating replica (the keysite) in the names. If this happens, you should rename the conflicting objects as soon as possible; see Resolving Naming Conflicts.
