  1. Ensure that any scheduled jobs on the deployment Advanced Options instance are disabled.

  2. Avoid conducting the deployment process during business hours to prevent user interference.

  3. Maintain a stable and fast internet connection throughout the deployment.

  4. Monitor the firewall for potential performance limitations that could impede the deployment process.

  5. Verify sufficient JVM resources and ensure adequate resource allocation, particularly JVM heap space. You can refer to the Jira Sizing guide: https://confluence.atlassian.com/jirakb/jira-server-sizing-guide-975033809.html and https://confluence.atlassian.com/enterprise/data-center-performance-946040735.html.

  6. Install the most recent version of the Configuration Manager for the Advanced Options app on both the source and target instances to access the latest features and bug fixes.

  7. When deploying a project with issues, avoid including attachment files in the snapshot to prevent unnecessary increases in snapshot file size increases. Instead, copy the attachments for the exported projects and move them to the target system. For more information, refer to the link: Move Attachments.

  8. Disable re-indexing in the advanced settings by default to prevent a non-locking reindex after importing the issues are imported, which is slow. If you disable it, the deployment will not start a reindex, and you will have to can start one yourself after the deployment is done. However, you can may also start a locking reindex after deployment, which should be considerably faster. For more information, refer to the link: Advanced Options.

  9. We kindly request you to schedule Schedule the deployment during off-business hours to enhance performance and reduce deployment time.

  10. Additionally, for Data Center users, please refer to our Data Center recommendations page - https://appfire.atlassian.net/wiki/spaces/CMJ/pages/82778043/Data+Center

  11. It is important essential to ensure that both the source and destination instances have sufficient resources allocated, especially the JVM heap. You can consult the Jira Sizing guide at https://confluence.atlassian.com/enterprise/jira-sizing-guide-461504623.html

  12. We recommend allocating Allocate double the recommended amount for the heap. Typically, 8-16 gigs GB of JVM heap are is sufficient for large migrations and, in some cases, even 32G32 GB.

  13. If you encounter performance issues with Jira Data Center during deployment, please refer to the following article articles for more details: More information:
