What should need to do after complete MCITP ?

These certifications prove that you have the comprehensive set of skills to perform a particular IT job role, such as database administrator or enterprise messaging administrator. They are based on older versions of Microsoft technologies, and your MCITP certification will decline in value as companies move to newer versions of our products. Take advantage of special upgrades to earn a Microsoft Certified Solutions Expert (MCSE) certification, and protect your investment in certifications.
