Error when trying to import scope through netsh

I'm trying to migrate a DHCP scope from a Win2003 server to another
Win2003 server. Followed the instructions in KB281626, but when I run the
netsh import command I get the folowing error:

Error while importing subnet "xxxxx."
This subnet already exists on the local server.

This scope is not the one I am trying to import.
Thanks for all the suggestions.
