Just to share my findings, I got a reply from VMware certification team:
"As I understand, you would like to enquire about the VCP-DCV 2022 Certification Requirements and I will certainly help you with this.
Please be informed that from the email id: xxxxxxx@yyyyyyy.com, I was able to track that you hold active VCP-DCV 2021 certificate.
In order to upgrade your VCP-DCV 2021 Certificate to VCP-DCV 2022 Certificate, I request you to complete the below requirements:
As per the policy, the candidates cannot complete the same course twice.
1.Attend one of the training courses in 2022:
- VMware vSphere: Troubleshooting [V7]
- VMware vSphere: Fast Track [V7]
- VMware vSphere: Advanced Administration Workshop [V7]
- VMware vSphere: Optimize and Scale plus Troubleshooting Fast Track [V7]
Or else.
2. Pass the Professional VMware vSphere 7.x (2V0-21.20) exam
Once you complete all the requirements, VCP-DCV 2022 certificate will be generated and it will be valid for lifetime."
I asked them to point me to document containing this policy. If I get it, I will add it to this post.
Best regards, Andrej
