Active Directory and DNS migration

I. PRE-MIGRATION

1. Migration planning
   • – number of network interface cards (NICs)
2. Prepare Source server
   • – back up
   • – collect migration data
3. Prepare Destination server
   • – install Windows Server 2012 R2
   • – assign temporary server name
   • – assign temporary IP address
   • – join domain

II. MIGRATION

1. Make Destination server a Domain Controller
2. Manually migrate DNS server settings
3. Transfer FSMO roles (faster with CMD):
   • Start CMD as Administrator
   • C:\Users\Administrator>ntdsutil
   • ntdsutil: roles
   • fsmo maintenance: connections
   • server connections: connect to server dc1 [dc1 is the name of the old server/FSMO master]
   • server connections: quit
   • fsmo maintenance: transfer naming master
   • fsmo maintenance: transfer infrastructure master
   • fsmo maintenance: transfer PDC
   • fsmo maintenance: transfer RID master
   • fsmo maintenance: transfer schema master
   • fsmo maintenance: quit
   • ntdsutil: quit
4. Migrate IP addresses and rename server
5. Perform verification steps

III. POST-MIGRATION (OPTIONAL)

1. Retire Source server
2. Roll-back migration
3. Troubleshoot migration
