Migrating existing services and server roles is an important part of the Server 2012 upgrade process. We have already demonstrated how to upgrade Active Directory Domain Services to Windows Server 2012
, and how to add an additional Server 2012 domain controller
In this step-by-step Screencast we demonstrate how to move your existing DHCP configuration and leases to DHCP 2012 Server. There are several ways you can perform this migration:
- using netsh utility (doesn’t export complex configurations – ex. multicast scopes)
- using Powershell Export/Import cmdlets in Server 2012 (same limitations as above, does not work with 2003 DHCP servers)
- using Server 2012 migration tools (requires extra admin efforts - installing server migration tools)
In our Screencast, we demonstrate the last approach – using Server 2012 migration tools (smigdeploy.exe). Although it requires some extra steps, it is the safest approach, working with all kinds of configurations and source servers. In our demo, we are moving the DHCP server role from a legacy 2003 R2 server to Windows Server 2012.
