If you already have your CCP version 6 links indexed by the search engine you may maintain your search engine positioning by telling the search engines where they may find things when you switch to CCP version 7.
The following rules are for Apache and will convert all CCP base and UK (GBU) URLs over with redirects. These rules would be applied above any SEO rules you have already in a .htaccess file for CCP. These assume you have standard SEO turned on in CCP version 6 and CCP version 7 and do not take into account HDSEO URLs – which probably won’t change from install to install.
