This guide describes the steps for migrating existing DHCP server
settings to a server that is running Windows Server 2012 R2. Migration
documentation and tools ease the migration of server role settings and
data from an existing server to a destination server that is running
Windows Server 2012 R2. By using the tools that are described in this
guide to migrate a DHCP server, you can simplify migration, reduce
migration time, increase the accuracy of the migration process, and
help eliminate possible conflicts that might otherwise occur during
DHCP migration.
