Recently, we upgraded Confluence to 4.0, the latest revision and was pleasantly surprised by the process. The upgrade was seamless, well documented, and no major issues found.
Upgrading confluence would have been really simple if we wanted to retain the same server. It’s a simple process:
- Stop the service
- Backup MySQL database
- Backup confluence application directory
- Backup data directory
- Upgrade any applications that are available to be upgraded
- Install the tar.gz from Confluence
- Start the process
- Wait around 10 minutes for indexes to be rebuilt.
However, we went a slightly different path, including an upgrade to Ubuntu OS 12.04 (from RHEL 5.0). Click here for our step by step process on upgrading Confluence from 3.8 to 4.0.
