For our newest credentials, such as Microsoft Certified Technical Specialist (MCTS), Microsoft Certified IT Professional (MCITP), and Microsoft Certified Professional Developer (MCPD), the credential retires along with the product support for the technology being tested. The credential will still appear on your transcript but will be listed as retired. In most cases, an upgrade path (usually one exam) will be available for individuals who have that credential so that they can demonstrate their skills on the newest version of the technology without completing all exams associated with the new credential.
The legacy Microsoft credentials, such as Microsoft Certified Systems Engineer (MCSE) and Microsoft Certified Systems Administrator (MCSA) do not expire, but as Microsoft releases new versions of the associated technology, these credentials are likely to be valued less by the industry.
