Before you begin
Step 1: Prepare for the upgrade
Make sure you have completed the steps in Preparing for the upgrade. These are mandatory pre-requisites, and are essential for a smooth upgrade.
Step 2: Choose your version
If you need help choosing the right version for you, head to the upgrade matrix to get a quick run down of features, supported platforms, and technical upgrade notes for all Jira versions.
Step 3: Stop the cluster
Omit this step if you're upgrading your Data Center with zero downtime.
Stop Jira on all nodes in the cluster. We also recommend that you configure your load balancer to redirect the traffic away from Jira until the upgrade is complete on all nodes.
Upgrade Jira on the first node
To avoid upgrading each of the nodes separately, you’ll just upgrade one of them, and make its installation directory a template. Then, you’ll copy this template to remaining nodes. You can choose any node here.
Step 1. Download Jira
- Download one of the Jira applications from our website. Choose the Windows or Linux binary.
If you're upgrading both Jira Software and Jira Service Desk, upgrade Jira Software only. You'll later upgrade Service Desk directly in Jira, without a separate installer.
Step 2. Start the installation wizard
The installation wizard will guide you through the upgrade process.
Run the installer you've downloaded.I'm using Windows...
a) Run the .exe file. We recommend using a Windows administrator account.
b) If prompted to allow the upgrade wizard to make changes to your computer, choose Yes. If you do not, the installation wizard will have restricted access to your operating system and any subsequent installation options will be limited.I'm using Linux...
a) Change to the directory where you downloaded Jira, then execute this command to make the installer executable:
$ chmod a+x atlassian-jira-X.X.X-x64.bin
X.X.Xis the Jira version you downloaded.
b) Run the installer – we recommend using
sudoto run the installer:
$ sudo ./atlassian-jira-X.X.X-x64.bin
You can also choose to run the installer with root user privileges.
- Follow the prompts in the wizard:
- When prompted, choose Upgrade an existing Jira installation.
- Make sure the Existing Jira installation directory suggested by the wizard is correct (especially important if you have multiple Jira installations on the same machine.)
- If you have already backed up the Jira home directory, clear the Back up the Jira home directory check box to avoid creating an extra backup.
The wizard notifies you of customizations in the Jira installation directory. Make a note of these as you'll need to reapply them later.
Your current customizations will be overwritten, but you can later copy them from your backups.
- When prompted, choose Upgrade an existing Jira installation.
In the last screen, the upgrade wizard will ask you to start the Jira instance and complete the upgrade. We recommend that you stop at this step, and complete the remaining steps from this page, up until Start Jira for the first time.
Starting Jira here won't affect your upgrade in any way, but Jira needs to be shut down to complete the remaining steps. Once you complete them, you can go back to the wizard and start Jira.
Step 3. Install the database driver
If you're using an Oracle or MySQL database, download a new JDBC driver. For other databases, you can omit this step.
If the driver is up to date, you can also copy it from your previous version.
Step 4: Re-apply any custom changes and increase pool-max-size
While using Jira, you’ve probably added some custom modifications to Jira files. These may include connection details, settings related to memory allocation, or other JVM arguments.
During the upgrade, the wizard migrated the following from your existing Jira installation:
- TCP values in the
- Location of your Jira home directory in the
- The following values in the
Apart from the above, you need to re-apply all other modifications. Here are the most important files:
setenv.bat(memory allocation and other JVM arguments)
- for more, see Important files in Jira
Re-apply your custom changes to your respective new Jira files by copying them from your backups.Make sure you don't just copy over the old files, as the 'native' settings they contain might have changed between the Jira versions.
If you're upgrading from Jira 7.x to Jira 8.x we recommend changing the pool-max-size parameter to 40 in your dbconfig.xml before the upgrade. Leaving the default of 20 can sometimes lead to “ResultSet Closed” errors during re-indexing on 8.x. For information on implementing the change, see Tuning database connections.
Step 5. Disable automatic reindex
This step is recommended when upgrading from Jira 7.x to Jira 8.x. If you're already on the 8.x line, you can omit this step.
Because of the changes to indexes that we've introduced in Jira 8.0, the index from any earlier Jira version will be incompatible after the upgrade. To create a new index, Jira will trigger an automatic reindex right after you start it. To avoid reindexing twice (after startup and after upgrading your apps), you can disable the automatic reindex, and run the second one later, whenever you’re ready.
Edit or create the following file:
Add the following line, and save the file:
Post-upgrade steps on the first node
Complete these post-upgrade steps only on the first node (the one you've just upgraded). The remaining nodes will later download the upgraded apps and index from the shared directory.
Step 1. Start Jira for the first time
Start your new Jira version, and connect it to the database.
- (Installer) Go back to your upgrade wizard and start Jira.
(Installer and Manual) You can also start Jira by going to
<installation-directory>/bin, and running one of the following files:
- Open Jira in your browser.
- Follow instructions on the screen to complete the setup.
Post-upgrade landing page
After a successful upgrade, you should see the post-upgrade landing page. It has some useful information about the new version, as shown below.
- Need to know: A list of new features that might affect your work as an admin.
- User apps: Status of your apps after the upgrade.
- Application links: Status of your application links.
- Release notes: Link to release notes where you can see more detailed information about the version you've upgraded to.
Step 2. (Optional) Update Jira Service Desk
If you're using Jira Service Desk, you can update it directly in the UI, without downloading a separate installer.
- Go to > Applications > Versions and licenses.
- Update Jira Service Desk. This will automatically update Service Desk to a compatible version.
Step 3. Upgrade apps (add-ons)
Now you can upgrade apps that had the Compatible once both are updated status. If you need more information about the statuses and apps in general, see Preparing for the upgrade.
- Go to > Manage apps > Manage apps.
- Upgrade your apps to the supported versions.
- Once the apps are upgraded, you can enable them.
Upgrading apps in a DC cluster
When upgrading apps, each node will pull the the most recently modified app jar file from the shared home on reboot.
To determine the file version, Jira uses the <version> value inside atlassian-plugin.xml. If there are multiple <version> values, Jira uses java.lang.String#compareTo to compare the different values.
Step 4. Rebuild index
Reindex Jira to recreate your index. This step might take some time, depending on how many issues and apps you have.
- Go to > Indexing, and run Lock Jira and rebuild reindex.
Step 5. Copy the upgraded Jira as a template
In this step, you'll copy the new installation directory with all the modifications you did so far. This will give you a template that you'll later copy to other nodes.
- Copy the new installation directory to some other location. This will be your template.
Upgrade remaining nodes
By now, you should have the ready Jira template, and upgraded add-ons and index data available in the shared directory. In this step, you'll copy the template to other nodes and start them one by one.
- Copy the template installation directory to the new node.
- If the path to the local home directory is different on this node, update it in the
- Start Jira on this node.
- Rinse & repeat: Repeat these steps on the next node.
Joining the cluster
You can check if the upgraded nodes are joining the cluster by going to> System > System info, and scrolling down to the Cluster nodes section.
You've upgraded Jira to a new version.
