Need to dig up an old issue briefly. The last time I tried to migrate a DHCP scope to an existing DHCP server (authorized and servicing scopes, but not in the same range as the ones being migrated over) I got an error “Error while importing option 6. This option conflicts with the existing option". Apparently this is the case because the already existing server added the entries for 006 DNS Server and 015 DNS Domain Name when it was installed/authorized. At the time the best recommendation I could find was to delete those two entries from the DHCP server options and then run the import (obviously DHCP scope would be exported from the source server) again. The last time I got around it because I had a server we could move the DHCP to that never had DHCP before and thus no previous entries existed. This time I have to move it to an existing DHCP server. However, I would like to understand what is the risk of deleting those two entries and has anyone ever done that step?
The other option would be to export only the v4 aspect of the scope since (as far as I understand it) the option for exporting specific scopes is split into v4 and v6 subcommands. So running something like this: netsh dhcp server v4 export c:\dhcp "192.168.1.0" might work because including the v4 portion of the command allows for the export of a single scope. This also gets around the "class conflicts with an existing class" error message that is returned when you try to import an entire scope on a server that already has DHCP configured. Many thanks in advance for all insights/input as always. Cheers!
