Hi Giles, You are getting the FeedMappingError.CANNOT_MODIFY_MAPPINGS_FOR_TYPED_FEED because the sitelink placeholder type is for the SITELINK <https://cases.corp.google.com/> feed type. Please take a look at the extension setting service migration steps <https://developers.google.com/adwords/api/docs/guides/extension-settings#migration_steps>. You will have to delete the old custom feeds and then use the extension setting service to create new SiteLinkFeedItem <https://developers.google.com/adwords/api/docs/reference/v201601/AdGroupExtensionSettingService.SitelinkFeedItem> s.
