Upgrade/Migration/Transitioning AD/Exchange 2003 Std to Ad/Exchange 2008 Ent. x64 Part I

1. Remove Antivirus from all “Server/ Servers” locations.

2. Assign new server IP Address:

IPAddress:

IP: x.x.x.x/nn

Gateway: x.x.x.x

DNS:

DNS : x.x.x.x (Old server as Primary)

DNS: x.x.x.x (Self IP asSecondary)

(**On New server make sure server windows firewall is disabled in order to ping it. OR put Exception to allow windows/ ICMP echo / Remote desktop/ DNS Traffic)

3. Check all the location servers connectivity to each other : Using “Ping”

Phase1-Preparing Old Server 2003 domain environment for Migration:

a / Raise Domain Functional Level:-

Go toàStart àAll Programsà Administrative Toolsà Active directory domains and trusts à Check domain functional level (r/c on domain name) àraise domain functional level to “windows server 2003” mode

(Note: requires Reboot then go to next step)

b/ Raise Forest Functional Level:-

Go toàStart àAll Programsà Administrative Toolsà Raise forest functional level (r/c on Active directory domains and trusts)à Raise domain functional level to “Windows server 2003”mode.

(Note: requires Reboot then go to next step)

(**Restart all location servers, so that updates can be replicated to all servers and make sure domain and forest functional level on all the servers are updated.)

c/ Extend Active Directory Schema Version :-

To check current schema version

à Start à Run à regedit à

HKEY_Local_Machine\Systems\currentcontrolset\services\NTDS\Parameters

Click on “Schema Version” it should be 30 or 31.

Copy ADprep32.exe from windows 2008 server CD to Old server in C: drive.

Go to > CMD >

# cd \adprep32

# adprep 32.exe /forestprep

Do not close the cmd, as we need it in next Step

Now Check the Schema Version

à Start à Run à regedità

HKEY_Local_Machine\Systems\currentcontrolset\services\NTDS\Parameters

Should be updated to 41

(**Check all other domain controllers for the same)

d/ Prepare Domain and Group Policy Level

Go to > CMD > cd \adprep32

# Adprep32 /domainprep /gpprep

e/ Install Windows Server 2003 Support Tools on Old Server :-

Open support tools command prompt

Startà All programs àWindows support toolsàCommand prompt

# netdom query fsmo

Check all following 5 roles to make sure it is primary DC:

1. Infrastructure Master Role

2. Naming Master Role

3. PDC Master Role

4. RID

5. Schema master

All 5 Roles should be with OLD server

Summary: - In this part we have prepared our Current AD environment to Install First Windows server 2008. Now in next step we will Install Windows server 2008 and will promote this server as primary DC by transferring all 5 FSMO roles to the new server. Also we will prepare, install and configure our Domain Environment for the Exchange Standard Server 2007 SP1.
