Thanks for the input guys. I was able to collocate the Config-Archives to a single share, which is nice. Looks like all I need to do is copy the following directories to the new polling engine.
<install area>\Orion\NCM\DeviceTypes\*.*
<install area>\Orion\NCM\Scripts\*.*
<install area>\Orion\NCM\Reports\*.*
<install area>\Orion\NCM\Jobs\*.*
