Problem
You’ve successfully completed a backup of an existing DHCP server’s DHCP database with the following command:
netsh dhcp server export c:\dhcp.txt all
However, when you attempt to import the backed up DHCP database onto the target server, you receive the following error:
netsh dhcp server import C:\dhcp.txt all
Error while importing option “15.”
This option conflicts with the existing option “” An internal error occurred.
Solution
One of the reasons why you may experience this issue is because the target DHCP server already has a option 015 DNS Domain Name configured:
In this situation, the easy way to fix the issue is to remove the defined option on the new DHCP server and try re-importing again.

Yep, that worked but I had to delete all Server options for the command to complete. Thanks for posting the solution!
This is not a viable solution and defeats the purpose of exporting and importing the configuration.
