If the URL for your site ever changes and comments aren't using a custom identifier, you need to use one of our available migration tools to relink comment threads to their proper URL. This will be necessary if you change domains, move to another blogging system, or if you're changing the permalink structure of your articles.
Go to your Disqus Admin and click Discussions > Tools > Migrate Threads.
The migration tools will NOT migrate comments to a new shortname, so be sure to use the same shortname on the new site.
Migration options available
- Domain Migration Wizard - If the base domain of your website has recently changed, you'll need to migrate the URLs of your commenting threads to use the new base domain (ex: www.old-url.com -> new-awesome-url.com).
- URL Mapper - If the URL slug of your site's posts has recently changed, you'll need to use our URL Mapper to migrate your commenting threads from the old URL to the new one (ex: yourdomain.com/p=23 -> yourdomain.com/new-page-slug).
- Redirect Crawler - If you've already setup 301 redirects for your site's pages, then use our Redirect Crawler to crawl your site's pages and migrate the URLs of your commenting threads automatically.
Note: Migrations can take up to 24 hours to finish, and we suggest checking its progress occasionally during that time (by looking for the updated comment threads on a page where they did not previously exist).
