The Novell DHCP Server for Linux is based on a standards-compliant implementation from ISC that is distributed with SUSE Linux Enterprise Server. DHCP uses a different schema on Linux to store the configuration in eDirectory.
After you set up Novell DHCP Server on the Open Enterprise Server SP1 and before you complete the cluster conversion, you can use the DHCP option for the Migration Tool to convert the configuration from NetWare to OES. You cannot directly reuse the data. Migrate your DHCP server data, then perform the post-migration tasks to set up the configuration in the OES nodes of the cluster.
