I have a SharePoint 2013 farm (multiple servers that connects to a sql cluster). The entire farm needs to move to a different AD domain. The SharePoint servers, the SQL cluster, the service accounts, and the users accounts. The old domain is being shut off, so everything needs to move. There is an article on support.microsoft.com that shows that moving the sql cluster is not supported.
I see forum posts saying that moving SP is not supported either, but can't find mention of this from official sources. I'm assuming I need to treat this like a migration and backup the content and service databases and restore them to a new farm that's been created in the new domain, but does anyone know of an official source of this info?
