Upgrade from Confluence Server to Data Center

If you're a current Confluence Server customer looking to upgrade to Confluence Data Center, this page will help you get a valid license and set up Data Center. There are several ways to get started with Confluence Data Center, depending on your current setup.

If you’re installing Confluence Data Center for the first time with no existing Confluence Server data to migrate, check out how to install a Confluence Data Center trial.

Set up Data Center

Things you should know about when setting up your Data Center:


It’s your Confluence license that determines the type of Confluence you have: Server or Data Center. Confluence will auto-detect the license type when you enter your license key, and automatically unlock any license-specific features.

To upgrade from Confluence Server to Confluence Data Center, you will need a Data Center license. You can either purchase a full Data Center license or get a free trial license for 30 days. When your 30-day trial finishes, you’ll have the option to purchase a Data Center license and carry on using Confluence Data Center without losing any data you’ve created during the trial. If you decide Confluence Data Center is not for you, you can easily revert to your existing Server license.

Note that as of February 15, 2024 PT, your Server products will reach the end of support

Supported platforms

See our Supported Platforms page for information on the database, Java, and operating systems you'll be able to use. These requirements are the same for Server and Data Center deployments.

Apps extend what your team can do with Atlassian applications, so it's important to make sure that your team can still use their apps after migrating to Data Center. When you switch to Data Center, you'll be required to switch to the Data Center compatible version of your apps, if one is available. 

See Evaluate apps for Data Center migration for more information.

If you plan to run Confluence Data Center in a cluster there are some additional infrastructure requirements. See Clustering with Confluence Data Center for more information.

During installation, you need to disable load balancer health checks and make sure you don’t open multiple tabs that point to the same Confluence URL.

Review and upgrade your apps

If you have any apps installed on your site, you'll need to upgrade to the Data Center app version, if one is available.
