VMware have announced the retirement of 4 exams related to the older version 5 certifications:
June 2, 2016
June 24, 2016
VCPC550 for VCP-Cloud
You won't be able to schedule any of these exams beyond those dates, so if you want to achieve those certifications you should act now!
If you already hold the certifications, or achieve them by the dates above, they won't be taken away from you. (VCP-Cloud falls under the VCP recertification guidelines/timing)
Each of the certifications above now has a newer version equivalent:
VCAP5-DCA > VCAP6-DCV Deploy
VCIX-NV > VCIX6-NV
VCAP5-DCD > VCAP6-DCV Design
VCP-Cloud > VCP6-CMA
The exams for the newer versions are either already available, or they will be before the retirement dates for the older version exams as above.
