  4. Some anti-virus or other Internet security tools may interfere with the JIRA upgrade process and prevent the process from completing successfully. If you experience or anticipate experiencing such an issue with your anti-virus/Internet security tool, disable this tool first before proceeding with the JIRA upgrade.
  5. Check for any known issues in the JIRAKB.
  6. If you have installed any additional JIRA plugins (i.e. not included with JIRA), please verify that they will be compatible with the version of JIRA you are upgrading to. You can find a plugin's compatibility information from the the plugin's home page on the Atlassian Plugin Exchange. Once you have confirmed the availability of compatible versions, you should upgrade your plugins after successfully upgrading JIRA. This can be done via the 'Plugin Repository' in your Administration Console.
  7. Test first!— We strongly recommend performing your upgrade in a test environment first. Do not upgrade your production JIRA server until you are satisfied that your test environment upgrade has been successful.
    • If you have any problems with your test environment upgrade which you cannot resolve, create an issue at our support site so that we can assist you.
    • If you have any problems during the upgrade of your production JIRA server, do not allow your users to start using this server. Instead:
      • Continue to use your old JIRA server — this will help ensure that you do not lose production data.
      • Also create an issue at our support site so that we can help you resolve the problems with production JIRA upgrade.
