When you clone an issue, a Cloners link type is created by default, and the cloned issue is linked to the original issue. This capability can be customized in a number of ways using Example clone-plus.properties. 

Steps to change link type and direction

1. Sign in to your Jira instance as Jira administrator.

2. In the top navigation bar, select JIRA Administration > Manage apps.
   The Manage apps page is displayed.

3. In the left sidebar of the Manage apps page, select Clone Plus for Jira.
   The Clone Plus for Jira Configuration page is displayed.

4. Select Clone plus properties > Edit tab to edit a copy of the currently active configuration.
   Or
   You can also create a clone-plus.properties file in the directory configured as your JIRA home directory or copy and modify the example clone-plus.properties file.

5. Add the following sample code for the 1 and 1.plus customized operations.

   1.linkType = Blocks # linkDirection default is OUTWARD 1.linkDirection = INWARD   1.plus.linkType = Blocks 1.plus.linkDirection = INWARD

6. Click Make Active.

7. Go to a Jira issue, and click Clone+ 1 or Clone++ 1.
   Once the Jira administrator has done these changes and the users clone any issue using the Clone+ 1 or Clone++ 1 clone operation, the link type and direction will be changed as defined.
