Remove trailing slash to save traffic (seo)

I’m running the latest version of Ghost and have trouble with a required trailing slash. I want to replace the already existing blog with a blog created with Ghost.
The previous blog is written without Ghost and its URL does not include a trailing slash. As I know, URLs with and without trailing slash are indexed as different URLs by Google. I guess that may cause traffic loss if I replace the existing URL without trailing slash with the Ghost blog with a required trailing slash. Are there any options available to save the traffic or to remove the trailing slash for the Ghost blog?

Since Ghost redirects non-slash to slash (e.g. /page to /page/), search engines will pick up the new URL over time, and incoming users will be redirected so they won’t see anything change :slight_smile:
