The MCSE exams are not dependent of a certain SQL Server version. In March they added questions to the exams that are about SQL Server 2014.
After a while, the certification will expire and you have to take the exams again (I think. I hope they have some actual upgrade exams at that point)
Need an answer? No, you need a question
