Not seen an official announcement on the VMware Education blog yet but when looking at the certification track for those people who are studying for their VCP-DCV and have taken a 6.7 version of a qualifying course already, VMware are stating that the 2V0-21.19 exam will be retiring on 31st December 2020.
After this date, students will need to attend a 7.0 version of one of the qualifying courses in order to meet the requirements for VCP-DCV.
