Clone Jira Work Management Category Field
Project Clone
Due to a change in the Jira API, it is currently not possible to clone Category field options with Project Clone. If you wish to clone Category values, you need to create field options manually before cloning the issues. We are investigating alternatives to restore this feature in Deep Clone for Jira.
Project Clone automates the cloning of Jira Work Management Category field options. By creating the options in the target project, the Category field values are also cloned along with the issues. Category colors are not cloned.

Other Clones
To clone the values of the Category field between projects, the values need to exist as field options in the target project. If these don’t already exist, you need to create the field options manually at least once before cloning your issues, so Deep Clone can set the field values.
