Exporting and Importing MS DNS Zones
Yes it's possible via the command line. Learn from my mistake. When you import the zone using the /primary option, it isn't AD integrated. And the /dsprimary option doesn't take a file parameter. :(
Export the zone from the source server.
Import the zone on the new server.
Make sure to change the zone to be AD Integrated
The /dsprimary flag used to create an AD integrated zone can't import a file for some reason. Just import as a regular zone and then change to AD integrated via the gui.
