URL Mapper sends visitors from addresses that no longer exist to new ones, instead of a "not found" page. Use it after moving or renaming pages, or after importing a site, so old links and search results still work.
ACP > Modules > Tools > URL Mapper
On the Mapped URL Browser tab, enter:
/old-page. A wildcard matches a whole directory: /pages/* matches /pages/one, /pages/two and so on.Mappings are only used when the address doesn't exist. The list shows how many visitors each one has forwarded.
