I just saw that I have passed exams “549 PRO: Designing and Developing Enterprise Applications by Using the Microsoft® .NET Framework” and “548 PRO: Designing and Developing Windows®-based Applications by Using the Microsoft® .NET Framework”. These exams were in beta when I took them and soon they are going to be available for everyone (if they are not already).
For everyone that needs to renew its certification, here is a link that explains the required exams and migration path from MCSD and MCAD to MCPD:
