Hi,
The MCITP certification will retire but not exam 640, 642 and 646. After July 31 passing these three exams will give you MCSA: Server 2008 instead of MCITP.

From MCSA: Server 2008 you can upprade to MCSA: Server 2012 by passing one additional exam, 70-417. This wil count for exam 410,411, and 412.

From MCSA: Server 2012 you need two more additional exams for MCSE: Server Infrastructure, 70-413 and 70-414
