Ahh, I bet it's a memory issue. The old server is a bit memory-strapped. It's looking more and more like a zip-like-tool is going to be what's needed. Thanks for the tip about memory--I bet that's it. Now I know I should pursue another route. Originally the intent with using BT Sync was that it could start weeks in advance and keep up with changes so that when deployment day came, it was basically done and up to date on this directory. And it was great for getting around the firewall.
