¿Cómo eliminar correctamente el foro de Discourse de un subdominio e Internet?

Hello,
First, I want to say that I love Discourse, but the forum I have didn’t really took off, so I want to know what’s the best wait to remove it from the internet.

The reason I’m asking is that the forum I have is a subdomain for the main website, so I want to make sure that anything I do won’t affect the SEO of the main site or Google.

Can someone give me an overview on how to go removing the forum? Do I have to deal with redirects? Will simply removing the forum will cause Google search problems with the main site? etc.

Thanks,

Simplemente puedes eliminar el subdominio, no se me ocurre nada que pueda afectar a otros sitios.
