Thank you - I’m researching how to do this. I am using mariaDB and it’s all running in docker, so I think if I can learn how to get terminal access within the docker container, and what commands I will need to access mariaDB, then I should be able to do so. I’m hoping that everything will be labeled in such a way that I can locate those records that are part of the carddav database only to clear them and start over.
