Your post needs moving to the VCP area of the Communities, so I have reported it to the volunteer moderators.
Choose the "VCP6.5-DCV or Older" path on this page for the answer to your question: https://www.vmware.com/learning/certification/vcp-dcv.html
Your existing VCP doesn't count towards the current VCP-DCV 2022, the path is the same as for a newbie.
