How to search and replace URL instances throughout topics?

[Nacho_Caballero]

Before I migrated my community, I had a bunch of topics with links to other parts of the community (https://my-old-url.com/t/whatever/63).

How can I search and replace all instances of my-old-url to my-new-url throughout all topics?
