I have a parent and a child domain.  DPS-ROOT  (dps-root.local) is the parent, DPS (dps.local) is the child.  I would like to eliminate DPS-ROOT entiterly.   All computers on the network are joinded to DPS, all user accounts and groups are in DPS.   Is it possible to simply "move" anything in DPS-ROOT to DPS and then get rid of DPS-ROOT?   or turn the child domain into the parent?

I'm assuming that DPS-ROOT is also your forest root (assuming this is not just a tree in an existing forest)
So it looks like DPS-ROOT is a typical empty root design (no users or workstations) just used to house schema and enterprise admins.  This was a very common design when AD first came out back in Windows 2000.  In fact many of us are still in forests that were setup that way.
You can't get rid of the forest root or turn the child into the forest root.
There is a tool/method to rename and reposition domains
The caveat there is that you can reposition every domain except the forest root
In a Windows Server 2003 forest, you cannot: Change which domain is the forest root domain
You could create a new forest and migrate all the objects over to it but really I don't think it is worth the hassle to do that.
