Last week I moved the site collection which is used as our Content Type Hub to a new web application. Simple enough, right? Well, I forgot one small thing; the Managed Metadata Service Application now needs updated so that the new location is used as the content type hub.
At first I opened up Central Admin and went to the MMS Properties, but of course the URL is grayed out with no way to edit it. Not to worry, of course there is a single Cmdlet in PowerShell that can do it!
Set-SPMetadataServiceApplication -Identity "<name>" -HubUri <url>
