Problems after upgrading to Jira 10

Symptom

You have recently upgraded your Jira instance to version 10. However, after this upgrade, you’ve encountered issues with the integration between Jira and Confluence, or possibly between two Jira instances, where the systems are no longer working together as expected.

Error: “Impossible to retrieve data from target remote server”

Cause

These integration issues are likely due to a compatibility mismatch between the version of Jira (10.x.x) and another Confluence or Jira instance you are currently using. Atlassian maintains a strict compatibility matrix between its products, and incompatible versions can lead to malfunctions.

Solution

1. Check your current Confluence and Jira versions:

   1. Access your Confluence instance and navigate to Administration > System Information to determine the exact version of Confluence

   2. For Jira, verify the versions of both instances involved by navigating to Administration > System Information on each Jira instance

2. Consult the Atlassian compatibility matrix:

   • Visit the official Jira compatibility matrix page: Jira Software 10.0.x Compatibility Matrix

   • Look up the version of Confluence or the version of the other Jira instance and verify if they are compatible with Jira 10.x.x

3. Possible actions:

   • If the versions are compatible: The issue may be due to another cause. In this case, it would be helpful to contact our support team

   • If the versions are not compatible:

     • Option 1: Upgrade Confluence or the second Jira instance to a version that is compatible with Jira 10.x.x

     • Option 2: Roll back to a previous version of Jira that is compatible with your current version of Confluence or the other Jira instance

4. Test the integration:

   • After making the necessary adjustments (either upgrading or rolling back), test the integration between Jira and Confluence, or between both Jira instances, to ensure that the systems are working together correctly

Additional recommendations:

Before upgrading Jira, Confluence, or integrating multiple Jira instances, it is highly recommended to check the compatibility matrix and conduct tests in a staging environment to avoid any service interruptions in production.
