I am trying to migrate from a Windows laptop to a MAC running on parallel. In our company, we use a domain controller running on Windows Server 2008 R2 for DNS/DHCP/Active Directory services. From previous experience with the migration, the DNS service keeps the old mapping record (IP->computer name) and does not recognize the new computer. Hence, the name of the new computer does not get map correctly to the IP address assigned. I am wondering what I can do during or after the migration to resolve the issue.
