When upgrading from an older Confluence version, where there is no crossover between supported platforms, you may need to upgrade via an intermediary version that supports both your current platform version and future one. For example, if you're running Confluence 5.4 with Oracle 11g and want to upgrade to Confluence 6.x which only supports Oracle 12c, you will need to upgrade via Confluence 5.7 where both Oracle 11g and 12c are supported:
- Upgrade to Confluence to 5.7
- Upgrade Oracle to 12c and check things run smoothly
- Upgrade to Confluence to 6.x

Collaborative editing with proxies and/or SSL
Collaborative editing is powered by Synchrony which synchronizes data in real time. Synchrony is executed as a separate process by Confluence Server and managed by Confluence automatically. Under normal circumstances, it should not need to be managed manually by an administrator.
You may, however need to make changes to your proxy configuration. We made significant improvements in Confluence 6.1, so recommend upgrading to that version or later if you plan to use collaborative editing.
Upgrade path
Upgrading from 6.0 or later
You can upgrade to any 8.x version at any time! Check the upgrade notes above to make sure everything is compatible, and you're prepared for the transition.
Use the table below to determine the most efficient upgrade path from your current version to the latest versions of Confluence.
Your Version | Recommended upgrade path to Confluence 9 |
|---|---|
| 2.7 or earlier | Upgrade to 2.7.4 then upgrade to 3.5.17, and follow paths below. |
| 2.8 to 3.4 | Upgrade to 3.5.17, and follow paths below. |
| 3.5 | Upgrade to 5.0.3, and follow paths below. |
4.0 to 4.3 | Upgrade to 5.10.x, and follow paths below. |
| 5.0 to 7.1 | Upgrade to 7.19.x, and follow paths below. |
| 7.2.x to 9.x | Upgrade directly to the latest version of Confluence 9. |
Before you begin, it's critical that you follow all of the steps in Upgrading Confluence. Confluence 8.x is a major upgrade, so it is important that you take a full backup, and test your upgrade in a non-production environment before upgrading your production site.
Post upgrade checklist
Once you have completed the steps required to upgrade your Confluence installation, check all the items on the Confluence post-upgrade checklist to ensure that everything works as expected. If something is not working correctly, check for known Confluence issues in the Upgrade Notes and try troubleshooting your upgrade as described.
