In place upgrade 2003 to 2008

Hi
Im looking for an outlline / whhitepaper detailing the steps to upgrade a
2003 DC to 2008. This is a test environment.

Thanks

Carl

 

Hi NGReader,

This won't go. The architecture of 2008 is too different to allow upgrade in
a sense that was available previously.
The best you can get is wipe-and-reload scenario.
You should follow the route:
1. Prepare your existing 2003 forest and domain for Win 2008 DC by using
ADPREP.
2. Install Win 2008 DC as an additional DC in your existing domain
3. Migrate GC, DNS and FSMO roles to the new DC.
4. Migrate other roles to the new Win 2008 Server(s).
4. Decomission the old DC.

There's plenty of information on Microsoft Technet
http://technet.microsoft.com/windowsserver/2008/default.aspx

Good luck

Hello NGReader,

You can do an inplace upgrade if at least SP1 for 2003 is installed.
http://technet.microsoft.com/en-us/library/cc732825.aspx

See also here about supported upgrade path's:
http://support.microsoft.com/?kbid=951041

Additional see here:
http://technet.microsoft.com/en-us/library/cc731188.aspx

As a small remark, i would install an additional 2008 DC/DNS/GC to the domain,
move the 5 FSMO roles, and copy the needed data to the new server. Fresh
install is always the better option, even if inplace is supported.

Best regards

Hello Dusko,

I do not agree with "This won't go. The architecture of 2008 is too different
to allow upgrade in a sense that was available previously". It is supported.

I agree with you that a fresh install as additional DC is the better option
to have a clean system without old OS parts on it.

Best regards

Hello NGReader,

Here are some steps for adding an additioanl DC to an existing domain:
!!!NEVER START BEFORE HAVING CREATED AND TESTED A BACKUP OF YOUR DATA/MACHINE!!!


- On the old server 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.

- if you are prompted for DNS configuration choose Yes. If not, install DNS
role after promotion.

- 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/library/cc772372.aspx)


Demoting the old DC (if needed)

- reconfigure your clients/servers that they not longer point to the old
DC/DNS server on the NIC

- to be sure that everything runs fine, disconnect the old DC from the network
and check with clients and servers the connectivity, logon and also with
one client a restart to see that everything is ok

- then run dcpromo to demote the old DC, if it works fine the machine will
move from the DC's OU to the computers container, where you can delete it
by hand. Can be that you got an error during demoting at the beginning, then
uncheck the Global catalog on that DC and try again

- check the DNS management console, that all entries from the machine are
disappeared or delete them by hand if the machine is off the network for ever

- also you have to start AD sites and services and delete the old servername
under the site, this will not be done during demotion
