Here's the situation. I have two farms PROD and DR. One of the scenario is to point DR farm to PROD database.
So basically SharePoint servers will be DR ones but database will be PROD one.
Is it possible? Because hostnames of both DR and PROD are different so I am thinking this will not work (as config database of PROD and DR is different) plus some shared service providers are working on PROD but not on DR.
But I see there is a connection string saved in registry of SharePoint server which points to Config database. So I was thinking to point this registry database to DR and then use alias (cliconfg) to point to content database on PROD. I am not sure if it is workable or not.
