Plan and execute a site migration, replatform, domain change or URL restructure without losing rankings, including the redirect map and the rollback. Use whenever the user mentions site migration, replatforming, domain change, URL restructure, changing a CMS, merging two sites, HTTPS migration, redirect map, 301 versus 302, redirect chains, or reports a traffic collapse after a relaunch. Also use before any change that alters URLs.
