Migrating DNS and Setting up DHCP

a little background on question.

i tasked setup active directory company after getting hired.

they have following setup:

dhcp being hosted server running dhcpd

there 3 domain controllers, dc01 needs demoted , have hits authentication key re-entered (was setup incorrectly). dc02 , dc03 having hardware migrated brand new server hardware.

i planning on doing following.

1. setup dc02's replacement brand new instance, migrate dns dc01, create new domain name subdomain (ex. corp.company.com), setup dhcp (to depreciate dhcpd), setup active directory. once new dc02 ready, shut down old dc02 , demote dc01 in order authenticate.

2. add dc01 part of forrest dc02, have replicate , balance load

3. setup dc03's new machine, depreciate dc03's old machine. replicate , load balance

questions:

1. how migrate dns existing dc new instance?

a. how plan subdomain being added?

2. can dhcpd migrated dhcp on win server 2012?

3. other details need consider?

thank in advance help, i'm learning go.

hi nema darban,

firstly need confirm fsmo role dc01 keeping, assume dc02 , dc03 additional dc.

if  dc01 pdc emulator can not migrate dns new dc2 directly, situation can use following procedure:
1.if dc3 doesn’t host fsmo role firstly move dc3 new hardware server.
2.transfer dc01 fsmo new hardware dc3 , migrate dns.
3.as want make dc02 child domain dc, can refer following kb demote dc child domain dc.
dcpromo demotion of last domain controller in child domain not succeed

4.enable dns zone replication between new hardware dc02( child domain corp.company.com).
5.install dhcp role on new hardware dc02
6.power offer old dc01 , dc02 test current environment has error, demote it.
