Hi folks, I have a server2003 server that I am going to migrate to server2008 (hurrah!), however, it has only got a single label for dns name. I have read somewhere this may complicate the migration. My questions are; As I am not going to be using Exchange, do I need to change this single lable for a dual label? Is it going to be easier to change the label before I migrate to server2008? Can the label be changed as I migrate to server2008? Thank you for your consideration.
