Hi @Zainab Arilesere,
In preparation for JIRA 7 we prepared some comprehensive documentation for people who had JIRA Agile (now JIRA Software) and JIRA Service Desk. You can find that comprehensive documentation here: https://confluence.atlassian.com/migration/jira-7/cloud_jira+agile+jsd_post-update-checklist
To answer the question that you have asked I think that you want to pay special attention to point 4 in the checklist. It should be able to help you achieve what you want to do.
If that does not answer your questions fully then please let me know and I'll be more than happy to answer further questions. Cheers!
