Moving posts between custom taxonomies

Hi There – I am trying to figure out if there is a way to move posts between custom taxonomies. I know in the old wordpress there was a plugin that let you convert pages to posts and vice versa. I have events, and when they are over I want to be able to turn them into products to sell videos of them without re-entering all of the information. Is that possible? I have searched all over and can’t find and answer.
