Drupal 7 to 8 Migration works only on the core, thus doesn't inlcude 301 redirects created in D7 with the Global redirect module.

Is there a workaround to migrate all the 301 redirects to Drupal 8 instead of coping them manually (after the site itself migrated successfully from D7 to D8) ?

The reason I ask this is because if I won't migrate these redirects, search engines that already indexed the old paths, will show 404's and these pages' SEO will most likely damage.
