How to Upgrade MCSE/MCSA 2003 to 2008 MCITP/MCTS

The certification on Windows Server 2008 system will use a new generation of certification system—MCTS and MCITP system.
It is known that the most concern of the candidates is how to upgrade MCSE 2000/2003 or MCSA 2000/2003 to credentials on Windows Server 2008 System. Here, to the best of my ability, I will give an enough detailed introduction.
 First of all, you could not be upgraded directly to the new certification system, if you just have MCSE 2000 or MCSA 2000.However, you can do, only if you have credentials on Windows Server 2003.And if you have MCSE (MCSA) certifications on Security or MCSE (MCSA) on Exchange, you must know that there aren’t both of the certifications on security and Exchange in the new certification system any more, which are covered in the new subjects.
Besides, there will be separate MCTS or MCITP on ISA or Exchange Server.
If you want to upgrade your MCSA on Windows Server 2003 to Windows Server 2008, you can choose the following paths. Certification roadmap
1. To get MCTS: Windows Server 2008 Active Directory and MCTS: Windows Server 2008 Network Infrastructure, you are required to pass 70-648.
That is to say:
MCSA 2003 +70-648 = MCTS: Windows Server 2008 Active Directory, Configuring
                                             + MCTS: Windows Server 2008 Network Infrastructure, Configuring
                                             = 70-640 +70- 642
2. To get MCTS: Windows Server 2008 Active Directory, Configuring、 MCTS: Windows Server 2008 Network Infrastructure and MCTS: Windows Server 2008 Applications Platform, Configuring, you are required to pass 70-649.
In other words:
MCSE +70-649 = MCTS: Windows Server 2008 Active Directory, Configuring
                      + MCTS: Windows Server 2008 Network Infrastructure, Configuring 
                     + MCTS: Windows Server 2008  Applications Platform, Configuring
                       = 70-640 +70- 642 +70-643
Notice: All of those upgrade exams could not upgrade you directly to MCITP.
So, if you have MCSA/MCSE 2003, you are required to pass the corresponding Pro exams to get MCITP.
1.If you want to get MCITP: server Administrator, you are required to pass both of 70-648 and 70-646.That is to say:
MCSA 2003 +70- 648 + 70-646 = MCITP: Server Administrator.
2.If you want to be upgraded to MCITP: Enterprise Administrator, you are required to pass four exams: 70-648, 70-643, 70-620 or 70-624 or 70-680, 70-647.
In other words:
MCSA 2003+ 648 + 643 + 620(or 624 or 70-680) + 647 = MCITP: Enterprise Administrator.
3.If you want to upgrade MCSE 2003 to MCITP Server Administrator, you are required to pass 70-649 and 70-646.
That is to say:
MCSE 2003+ 70- 649 + 70-646 = MCITP: Server Administrator.
4.If you want to be upgraded to MCITP: Enterprise Administrator, you are required to pass three exams: 70-649, 70-620 or 70-624 or 70-680, 70-647.
In other words:
MCSE 2003+70-649 +70-620(or 624 or 70-680) + 647 = MCITP: Enterprise Administrator.
My advice: if you are prepared for MCSE, and want to be upgraded to Credentials on Windows Server 2008, you’d better pass 70-620 instead of the popular exam 70-270 as MCSE exam on client operating systems client operating systems
Besides, I think it is necessary to know about Microsoft’s new certification on Windows Server 2008 system.
MCTS：Focused on configuring and troubleshooting key technologies
MCITP：Focused on advanced infrastructure design
MCTS credentials on Windows Server 2008 will involve the following aspects:
1、 Active Directory Domain Services AD
2、 Identity and Access Management
3、 Internet Services
4、 Terminal Services
5、 Networking Infrastructure
As was mentioned above, MCTS credentials on Windows Server 2008 systems have three exams, which aim to measure the skills on AD ,SA（System Architecture），application.
MCITP credentials on Windows Server 2008 will involve the aspects below:
1. Infrastructure Operations
