1. Backup the existing zone to a zone file. Resulting file will always be placed in C:\Windows\system32\dns – this can’t be controlled:
dnscmd /zoneexport zone.local

2. To restore the zone, move the file back into C:\Windows\system32\dns then:
dnscmd /zoneadd zone.local /primary /file /load

And finally, convert it into an AD integrated zone:
dnscmd /zoneresettype zone.local /dsprimary
