If I update my help center’s subdomain, will that change the rest of the article URL? (ID and/or title bit)

Hi guys! Does anyone know if I update my help center’s subdomain, will that change the rest of the article URL? (ID and/or title bit)

To offer a bit more context: we're moving our help center over to Intercom, however the domain we'll eventually be using is already in use for our existing help center (help.company.com).

I'd like to update all of the links inside our articles to use the Intercom article URLs prior to moving the site to our official support domain. The Intercom help center is currently set up on the temporary subdomain newhelp.company.com.

I'm currently replacing the article links using the Intercom article URLs but removing the 'new' part so that the links should just work once the domain is moved over.

However if the article URLs (ID or titles etc.) will change when we update the subdomain, this means we'll have to redo the link URL updates while the articles are live, meaning there will be a period of time where links within all 250+ support articles are broken.

Any help/suggestions appreciated.
