We had the same issue and built an isolated network (spanning two 
buildings! ugh) with its own DNS and NTP server.  The DMA was put on 
that DNS server and then CUCM pointed to it as an SFTP source.  Test 
network used the same subnets as production so that we could then drop 
it all into place after the build-out was complete.

I know you're not asking me, but I think  you should build out the 
above-described network from the start.  It worked well for us but tied 
up some switches and infrastructure so that our inventory people hounded 
us for a while to return the parts.
