Windows 2003/Exchange 2003 upgrade to 2008R2/Exchange2010 solution

Solution Description:
In order to meet the development requirements, a factory plans to upgrade the existing domain and mail environment from the original 2003 to Windows 2008 R2 and Exchange 2010. Slot upgrade, the impact on the user is minimized, does not affect the normal work of the factory!
Existing Environment:
Two AD servers are DC01/DC02, hardware configuration: DELL1950 146G*2 Raid1/1G memory, running Windows 2003 SP2.
An Exchange Server Mail01, hardware configuration: DELL2950 146G*5 Raid5/1G memory running Windows 2003 SP2+ Exchange 2003 SP2. To meet the needs of 2008 R2 64x and Exchange 2010, the AD server memory was upgraded to 6G, and the Exchange server memory was upgraded to 8G.
The specific operation is as follows:
1. Change the domain operation mode, transfer the five major roles of AD and GC to DC02, demote DC01 with DCPROMO and exit the domain. 2. Install DCR64 64x operating system and add domain 3.

Perform DCPROMO upgrade on DC01 to 2008R2 domain controller and set it to GC< Br> 5, transfer the five major discoloration of AD to DC01
6, downgrade DC02 with DCPROMO and exit the domain

7. Install DC02 to install 2008 R2 64x operating system and add domain 8. Execute on DC02 DCPROMO is upgraded to 2008 R2 domain controller and set to GC 9. At this point, AD2003 upgrades 2008 R2 work is completed. 10. In order to ensure the smooth transition of Exchange, first find a free machine, install Windows2003 and Exchange2003, set to Mail02. 11, transfer Mail01 mailbox, public folder, etc. to Mail02 12.
