Hi! My Network Environment has as bellow - A Windows 2003 R2 Standard Edition X86 for Domain Controller. - A Windows 2003 R2 Standard Edition X64 for Microsoft Exchange 2007 Server. - Over 100 Users both Windows XP and Windows 7 Client. And now i want to migration my Network Environment as bellow: - A Windows 2008 Standard Edition X86 for Domain Controller. - A Windows 2008 Standard Edition X64 for Microsoft Exchange 2007 Server. (Can we use Windows 2008 SE x86 for Exchange 2007?) - Over 100 Users both Windows XP and Windows 7 Client. My question is, How can I migration from W2k3 to W2k8? and what are they effective with my Network Environment?

Hello, for AD, you have to upgrade to AD DS 2008: http://technet.microsoft.com/en-us/library/cc731188(WS.10).aspx How many DCs do you have? If it is just one DC then you can proceed using one of the following: Perform an in-place upgrade of your DC to 2008: Perform a backup of your DC before proceeding Add an additional DC and make it a DNS and GC server. Once done, check that AD replication was done without problems, transfer FSMO roles and demote the old DC (recommended) If you have multiple DCs then make sure that you have at least one DC / DNS / GC server and transfer FSMO roles to it, demote all other DCs, re-install their OS and promote it again. Continue like that untill you upgrade all DCs. For Exchange, please ask them in Exchange forum: http://social.technet.microsoft.com/Forums/en-US/category/exchangeserver Note that it is recommended to have at least two DC / DNS / GC servers per domain.

In my network environment I have only a DC and a Exchange 2007 server So I need to Install Addition domain for my Domain Controller right? please give me some idea about it. thanks

I cannot see the most important information. Are you migrating old operating system to the new one on the same hardware, or you are migrating to new hardware. If you have new hardware, then you should use 32 bit version of adprep (see the Technet on the procedure for forest, domain and group policy) add W2K8 to the domain, make it domain controller and move the FSMO roles and replicate GC. Do not continue with Exchange migration, until the system is fully replicated and logs without error. Then you follow advise from Exchange forum, how to optimally migrate Exchange server. You should have advice on the Exchange prior to the any migration step.

Here is the step by step guide for the Migration by Mienolf Weber which is very much to the point and easy http://msmvps.com/blogs/mweber/archive/2010/02/10/upgrading-an-active-directory-domain-from-windows-server-2003-to-windows-server-2008-or-windows-server-2008-r2.aspx for exchange realted queries seek guidance here http://social.technet.microsoft.com/Forums/en/exchangesvrdeploy/threads http://www.virmansec.com/blogs/skhairuddin

In addition, After completing the forestprep check the schema version and wait for the completeing the replication and then run the domainprep. How to check the schema version? http://support.microsoft.com/kb/556086 Schema version for new operation system Find the Schema version for the operating systems 13 - Windows 2000 Server 30 - Windows Server 2003 RTM, Windows 2003 With Service Pack 1, Windows 2003 With Service Pack 2 31 -Windows Server 2003 R2 44 - Windows Server 2008 RTM 47 - Windows Server 2008 R2 ________________________________ Take the system state backup of your schema master then disable the outbound replication and run the forestprep. Repadmin /options <dc-fqdn> +DISABLE_OUTBOUND_REPL After getting the success log enable the out bound replication via repadmin. Repadmin /options <dc-fqdn> -DISABLE_OUTBOUND_REPL Wait for competing the replication. > Using the copied folder on each DC run the following commands in the order specified in the following table. Use adprep32 since the OS on the DC is assumed to be 32bit. Command Permission Domain Controller Runtime adprep /forestprep Schema and Enterprise Admin Schema Master 3-5 mins adprep /rodcprep Schema and Enterprise Admin Domain Naming Master Seconds adprep /domainprep /gpprep Domain Admin Infrastructure Master Seconds > Check the following log file on each DC to verify there were no errors. %SystemRoot%\Debug\adprep\logs\yyyymmddhhmmss\adprep.log > If you run adprep multiple times on a DC then a new log is created for each run.

You have some more GUI options in Windows server 2008, for example an AttibuteEditor tab on the user/machine account properties and the new AD AC for example. http://technet.microsoft.com/en-us/library/cc753208(WS.10).aspxBest regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
