I am creating the localization sites /en using the Set-TtmMapping -RelativeUrl but getting the error. Any Suggestion would be highly appreciated.

And When trying to update the publication URL from CMS gets error

Just set the Publication URL (in CM) to empty. That makes it "context-relative" instead of server-relative, meaning that there is no longer an overlap between the part of the URL managed in Topology Manager and in Content Manager.

Likewise, the "Multimedia URL" should be changed to be context-relative by ensuring it does not start with a slash (and it does not contain the RelativeUrl of the TTM Mapping).

  • Also you have option to mention your "RelativeUrl (URL path segment) in your Publishing property of Publication. Oct 3, 2016 at 19:17
