Is there a best practice for upgrading a domain with an Underscore in the name (domain_name)? Are the only options to either attempt to rename the domain or migrate to a new domain?

    Hi,

    It's possible to rename a domain but the recommended method is to migrate to new domain.

    Some applications doesn't support the domain rename, you can refer to the following link talking about some risk you can get when you rename a domain:
