Windows 2008 R2 DHCP scope change - Netsh Exec not working

Question

OK, there seems to be a disconnect between Netsh documentation and how it actually works.  We are in the process of re-addressing ALL our DHCP scopes (joys of a buy-out) and using the steps outlined in numerous MS articles and Blogs etc... we should
be able to use "Netsh dhcp server scope 192.168.1.0 dump > scope1.cfg"  then modify the cfg file with the new scope address (i.e. change all 192.168.1. to lets say 10.10.5.).  Then use netsh exec scope1.cfg (yes, the file modified) to
create the new scope which would contain all the "stuff" the current scope has (reservations, options, etc).  
Well, all we get is the response "The following command was not found:   |".  
Environment is as follows:
Account is a domain admin
working on a RDP session on the DHCP server
Server is Windows 2008 R2 (current functioning DHCP server)
Using administrative CMD (elevated)
have tried changing context into Netsh | DHCP | Server and default CMD - all "no go"

There's a lot of discussions around this, but I haven't seen any response that says how to actually do it.  export/import won't work for us since we have to update the scope info.  With almost 100 scopes to update, we really need this functionality!
(or similar method)
Any assistance would be greatly appreciated.

OK...  It seems the issue is with the dump file.  I actually got exec to run once with a dump file which wasn't modified.  The stupid part is it only ran one time, I could not duplicate it.   Since
I've beat this thing to death and no one could offer any assistance (Hello MS?), I'm not wasting any more time on it.   Luckily, I was able to figure out an alternate method.  
Looking at the dump file I realized all the lines are just a straight NetSh commands, which means all I needed to do is grab the lines and preface them with NetSh.  Like this...
for /f "tokens=*" %a in ('type scope.cfg ^| find /i "dhcp"') do NetSh %a
where scope.cfg is your dump file.   This runs perfect and seems to be the exact thing that exec should be doing.  I did flip the "SET STATE 1" to "0" so the scope was deactivated  (Don't forget to run it in an elevated
prompt).
Hope this helps someone else so they aren't spending days for nothing!
