Traffic redirection

Hi,

I recently moved my free WP blog https://saskiapaul.wordpress.com/ to a new domain
https://saskiapaul-globetrotter.com/.

Now, I would like to direct any traffic from the free WP blog automatically to the new URL. What is the best way to do that? And should I redirect only the landing page or do I have to implement a redirect from any subpage of the old blog?

Thanks,
Paul
