7. After maintenance is completed test need to be done by a Jira Administrator to confirm if it was succesfull:
   Confluence
   
   Jira
   1. Check if customer portal is available and if a ticket can be raised:  https://support.yamnet.com/. Close ticket when succesfully received.
   2. Look for a Dashboard
   3. Look at several boards, Scrum and Kanban if these are loading and have correct filters
   4. Open existing SD ticket and check if you see attachments
   5. Open existing SD ticket and check if you see links
   6. Open existing B2B ticket and try to jump to Bitbucket via create branche.
      More - Create branche
      
   7. Confluence: Open a page and select Edit
      Link a Jira ticket to Confluence page and check if link is appearing in Confluence and in Jira issue.
      
   8. Check messages for compatibility on applications 
      
      
   9. If all of above is succesfull inform stakeholders that maintance/upgrade was succesfull. (for stakeholders see point 6)
