Hi @Sam Tsubota , we had configured the setup very similiar to the mentioned article using an acceptance date. The article was helpful, we also added clear post-functions from "done" to other states. We introduced the change as an improvement to an existing configuration and wanted also to migrate older tickets. This step might be necessary at other customers as well. "Migration" means: the accepted data needs to be set for already done issues. For this we introduced a (temporary) workflow transitions that copies the resolution date to the acceptance date. Having this workflow transition we could bulk change a lot of tickets.
