Win2008 transition

Hi,

We are in the process of transitioning to win2008. All DNS secondary entry
point to the main office DC. I would like to do a fresh Win2008 install for
all DCs starting with the main office DCs .Since we are on a tight budget no
new hardware is available just one swing box . I was planning on using the
swing box to install the first Win2008 DC in the main office, move all FSMOs
and my backout paln is to power off the old Win2003 DC in the main office
for a couple days just to make sure there are no issues . Also we need to
keep the same DC server names and ip addresses when we install the new DCs
(Win2008) .that being said I have couple questions...

a) Since all DNS secondary point to the Win2003 DC in the main office if I
shut down this server for a couple days will there be issues ?
b) After I rebuild my old win2003 DC to Win2008 using the same DC computer
name and ip address and move all FSMOs back to this box can dcpromo my first
Win2008 DC I wipe my swing box clean? Any items I need to make note of
before I wipe my first Win2008 DC ?

Thanks in advance for your help..

Hello southpaw,

a: Shouldn't be an issue, when the secondary DNS is not reachable as long
as the other is

b: For all steps with migration to 2008 and keeping the names make sure that
after every step the changes are replicated within AD to all DC's and also
in DNS. So use the support tools before during and at the end of the transition.

Assuming that the "swing" machine will not stay and have to use one of the
old name, your way sounds ok. Also with powering down or just disconnecting
from the network you do a good step to make sure it will still work.

Is there Exchange running on a DC or any other application like SQL?

See here for some details:
!!!NEVER START BEFORE HAVING CREATED AND TESTED A BACKUP OF YOUR DATA/MACHINE!!!

- Open DNS management console and check that you are running Active directory
integrated zone (easier for replication, if you have more then one DNS server)

- run replmon from the run line or repadmin /showrepl(only if more then one
DC exist), dcdiag and netdiag from the command prompt on the old machine
to check for errors, if you have some post the complete output from the command
here or solve them first. For this tools you have to install the support\tools\suptools.msi
from the 2003 installation disk.

- run adprep /forestprep and adprep /domainprep and adprep /rodcprep from
the 2008 installation disk against the 2003 schema master, with an account
that is member of the Schema admins, to upgrade the schema to the new version
(44), you can check the version with "schupgr" in a command prompt.

- Install the new machine as a member server in your existing domain

- configure a fixed ip and set the preferred DNS server to the old DNS server
only

- run dcpromo and follow the wizard to add the 2008 server to an existing
domain, make it also Global catalog and DNS server.

- for DNS give the server time for replication, at least 15 minutes. Because
you use Active directory integrated zones it will automatically replicate
the zones to the new server. Open DNS management console to check that they
appear

- if the new machine is domain controller and DNS server run again replmon,
dcdiag and netdiag (copy the netdiag from the 2003 to 2008, will work) on
both domain controllers

- Transfer, NOT seize the 5 FSMO roles to the new Domain controller (http://support.microsoft.com/kb/324801
applies also for 2008)

- you can see in the event viewer (Directory service) that the roles are
transferred, also give it some time

- reconfigure the DNS configuration on your NIC of the 2008 server, preferred
DNS itself, secondary the old one

- if you use DHCP do not forget to reconfigure the scope settings to point
to the new installed DNS server

- export and import of DHCP database for 2008 choose "netshell dhcp backup"
and "netshell dhcp restore" command (http://technet.microsoft.com/en-us/l.../cc772372.aspx)

Hi Meinolf,

Thank you for the info.. this is all great stuff !..certainly appreciate the
feedback...
btw.. I have a another question...
Since there are no funds for new servers and will be rebuilding all DC with
windows 2008 . I just realize most if not all our DC's there are no DVD
drives and was wondering what would be the easiest way to go about getting
Windows 2008 on these box.es We have about 25 DC's in various offices with
some local support. I read some where i can boot of a usb/flash drive
assuming the Bios will support such boot.. Any other ideas.?. I'll also have
to do the same in the remote offices not a problem but wanted to know my
options...

Also just to clarify I will be using a swing box to install the first
Windows 2008 DC in the domain and wanted to know if there are any issues
wiping my first Windows 2008 box after the other Windows 2003 boxes have
been rebuilt with Win2008 assuming FSMO etc have all been transferred...I
don't believe there will be any issues but just wanted to check...

Is there Exchange running on a DC or any other application like SQL? no
exchange or SQL apps on DC's thank god ...:-)

Thanks again ....

Hello southpaw,

See here about USB:
http://www.jesscoburn.com/archives/2...sb-thumbdrive/

What about buying a small DVD USB drive? Or maybe some of your office admins/users
has one you can borrow?
