title: Backing up and restoring a sharepoint content database across two machines, hosed my sharepoint app
body: <p>I have sharepoint sites provisioned on two machines A and B. I would like to take the content database from machine A and restore it into the site on machine B.
  I used SQL backup to backup machine A's database, and restored it to machine B, overwriting the existing content database. However, my sharepoint site became unreachable - I would get a generic site not found error. Did I also have to back up and restore SharePoint_Config database too?
  What is the best practices for this kind of scenario?</p>
