You can copy the value of a source field to a destination field. Click the + button to add additional field pairs to your configuration.
Keep in mind that not all conversions from source to destination field are supported, nor feasible. We can only ensure that it will work if the source and destination fields are of the same field type, or the destination field is a text field. (Some additional combinations of different field types might work although not 'officially' supported.)
For text fields and other fields that can accept multiple values (like checkboxes), you can choose to overwrite, append, or prepend the new value to any existing value. In the case of a text field, you can also choose a separator that will be placed between the values (not shown in the screenshot above). Imagine your origin issue has a version, and that you want to copy to the linked issue. If the destination field is 'Fix Version/s', 'Affects Version/s' or some custom field of type 'Version Picker', you can choose that a new version will be created in the target project, if it does not yet exist. If you don't choose this option and that version does not yet exist, the user will get an error message and the transition will complete. However be aware, that a user needs the 'Administer Projects' permission to be able to create a new version. Imagine your origin issue has a component, that you want to copy to the linked issue. If the destination field is 'Components', you can choose that a new component will be created in the target project, if it does not yet exist. If you don't choose this option and that component does not yet exist, the user will get an error message and the transition will complete. Note that a user needs the 'Administer Projects' permission to create a new component. For source, you have some additional options: For destination, you have also special options:Overwrite / Append / Prepend
Create version if necessary
Create component if necessary
Special 'Sources'
Special 'Destinations'
Example:Copy Description to New Comment, overwrite
→ creates a new comment with the descriptionCopy Summary to New Comment, append with separator ", "
→ appends the summary to the previously created comment, so the comment will look like <Description>, <Summary>Copy Assignee to New Comment, overwrite
→ creates a new comment
This configuration will result in two comments being created, one with the description and summary, and one with the assignee.
