How to Migrate/Move one DC to another

-

hi,

i need know how migrate existing domain controller newly created 1 remove old 1 dc , leave file/print server terminal services users can access apps still via rdc. want move roles dns\dhcp\wins new server , make gc. want extremely careful , step step guide good.

what i've done far is:

  • built new windows server 2003 , installed updates , joined existing domain , run dcpromo , added additional domain controller.

is there order transfering roles? ie; dns first, dhcp etc..

 

 

hi there,
 
scenario 1.
 
old dc: windows server 2003 r2 (to decommissioned)
new dc: windows server 2003 r2
 
assumed have other available dcs in environment , can install new windows server 2003 r2 on new computer , introduce additional domain controller in current windows server 2003 domain, may demote old windows server 2003 dc.
 
for convenience, have list general steps reference.
 
since following operation have potential damage active directory database, highly suggested you'd better perform full backup of active directory (system state) firstly. better test following procedure in similar lab environment first.
 
general steps:
=============
 
1. verify new server's tcp/ip configuration has been pointed current dns server.
 
2. make new server become member server of current windows server 2003 domain first.
 
3. run "dcpromo" on new server promote additional domain controller in existing windows 2003 domain, afterwards may verify installation of active directory.
 
please refer to:

how verify active directory installation in windows server 2003
http://support.microsoft.com/kb/816106
 
4. verify new server's tcp/ip configuration has been pointed current dns server.
 
5. if have dhcp server migrate, suggested perform dhcp database migration before promoting domain controller.
 
6. export dhcp database current dhcp server using dhcp export import utility (dhcpexim.exe). may migrate dhcp database windows 2003 domain controller.
 
7. install dhcp server service on new server running windows server 2003 if necessary. import dhcp database new dhcp server
 
please refer to:
 
how move dhcp database computer running windows nt server 4.0, windows 2000, or windows server 2003 computer running windows server 2003
http://support.microsoft.com/kb/325473
 
8. adjust dhcp scope settings make them use new dns server.
 
9. unauthorize old dhcp server , authorize new dhcp server , new 1 can work within active directory.
 
10. insert windows server 2003 r2 installation disc in new server.
 
11. run "dcpromo" on new server promote additional domain controller in existing windows 2003 domain, afterwards may verify installation of active directory.
 
12. enable global catalog on new server , manually check replication topology , afterwards manually trigger replication (replicate now) synchronize active directory database between 2 replicas.
 
please note: time replicate gc between dc, please wait time patience.
 
13. disable global catalog on old dc.
 
14. transfer fsmo roles old dc new dc.
 
please refer to:

how view , transfer fsmo roles in windows server 2003
http://support.microsoft.com/kb/324801
 
15. verify old dns server zone type active directory-integrated. if not, please refer to:
 
how to: convert dns primary server active directory integrated
http://support.microsoft.com/kb/816101
 
note: active directory integrated-zone available if dns server domain controller.
 
16. install dns component on new server , configure new dns server (active directory integrated-zone preferred). dns configuration should replicated new dns server active directory replication.
 
17. make clients change tcp/ip configuration point new server dns.
 
18. may configure tcp/ip on clients, or adjust dhcp scope settings make them use new dns server.
 
19. afterwards, may run "dcpromo" on old dc follow wizard demote it.
 
please note: practice make old dc offline several days , check whether works new server online. if so, may let old dc online , run dcpromo demote it.
 
scenario 2.
 
one box: windows server 2003 domain
 
assumed want totally install new windows server 2003 r2 domain on old box. please make sure application , data needed have been backup , resource in active directory isn't need anymore. may demote windows server 2003 domain , perform in-place upgrade windows server 2003 r2.
 
please refer to:
 
how upgrade windows server 2003 service pack 1 windows server 2003 r2
http://support.microsoft.com/kb/912309
 
afterwards, may promote windows server 2003 r2 box new dc "dcpromo"
 
hope helps.
