If you clone an epic in Jira with epic clone a screen will be displayed where you can make your configuration of the cloned epic and issues. On this page it is explained what you can do on this screen. Let's assume we want to clone this epic with epic clone:
It contains 4 issues in epic, has 2 sub-tasks, one linked issue, one attachment and a value for original estimate. If you now select more → Clone Epic Template you will get the epic clone configuration screen which will be explained in the following.
To Project: Select the target project for your clone. You will only see projects in the select list you have access to and which have the epic issue type configured.
Summary: Set the summary for the cloned epic. The summary of the source epic is displayed by default.
Epic Name: Set the epic name field for the cloned epic. The epic name of the source epic is displayed by default.
In Description: Find & Replace functionality for description field. This is especially useful if you have placeholders in your source/template epic description. Then just insert the placeholder in find and the desired value in the target epic in replace and the description in the cloned epic will be set accordingly.
Fix Version/s: Set the fix version/s field in your cloned epic. The fix version/s value of the source epic is displayed by default if a version is set. Please not that the fix version/s you select here will be set also in all issues in epic. The select list will show all available versions in the target project (see to project field on top).
Original Estimate: Set the original estimate for the cloned epic. The estimation value of the source epic is displayed by default if it has a value set.
Due Date: Set the due date for the cloned epic.
Clone Attachments: Check this if you want the attachments of the epic to be cloned as well.
If you click on next you will get to the second page where you can configure the issues in epic.
Issues in Epic
All issues in epic are listed on this screen. The issue type icon, key and summary are displayed. With the checkbox in front of the different issues you can decide whether they shall be cloned or not. Furthermore, some additional information can be set here:
Original Estimate: Set the original estimate for the different issues in epic which will be cloned. The estimation value of the source issue is displayed by default if it has a value set.
Due Date: Set the due date for the different issues in epic which will be cloned.
Assignee: Select the assignee for the different issues in epic which will be cloned. Only users with assignable user permission in target project can be selected here.
If the epic has sub-tasks they will be displayed in a list below the issues in epic section with issue type icon, key and summary. Similar to the issues in epic you can choose via the checkbox if they shall be cloned as well or not. If the checkbox is checked they will be cloned as sub-tasks in the target epic.
If the epic has issues linked to it, they will be displayed in a list below the sub-tasks section. As for issues in epic and sub-tasks you can also decide for linked issues if they shall be cloned or not. Please note that if the checkbox is checked those issues will be cloned and the cloned issue will be linked to the target epic.
Summary Pre- and Postfix
For the summary of the issues in epic, sub-tasks or linked issues, you can optionally set a pre- or postfix in the two fields on the right side. If you insert something there, the pre- or postfix will be shown immediately before or after the issues summaries on the left side, respectively.
If you finished your settings, just press the "Start Clone" button to start the cloning process.
Please note that regardless if the issues in epic or linked issues are located in different projects or not in the same project than the source epic, all issues will be cloned to the project selected in the "to project" field (= target project).
If the cloning is finished the results are displayed and you can go to the newly created epic or issues by clicking on the respective links.
