If I correctly understand the problem _a posteriori_, the [doc](https://meta.discourse.org/t/change-the-domain-name-or-rename-your-discourse/16098) could suggest to remove all old occurrences of `talk.bar.com` prior to launch this command. It could simply done via

```plaintext
discourse remap talk.bar.com talk.foo-or-bar-that-s-the-question.com

```

(I didn’t tried.)
