I have read the other postings about this but have yet to have success. We have a project with an issue type and its associated workflow that we want to keep in place, i.e. do not want to migrate existing issues to another workflow or change them to another issue type. We created a new issue type and its new associated workflow. Now, we want to add them to the same project. But, it's as if we cannot have more than one in the same project, or Jira (Data Center) sends us into steps of migrating the existing issues to the new issue type or new workflow. Any ideas? Shall I delete the new issue type and new workflow and try again?
