How to upgrade Confluence 3.5.6 to 3.5.9


I'm new to this and have a test environment that I would like to upgrade to ver. 3.5.9 (same as our prod environment).

I have searched online to see if it is possible to do an inplace-upgrade, but haven't found anything.
How should this be done?

* Inplace-upgrade
upgrade binaries, service

* new install
install new version side-by-side, backup old and restore to new, new service, uninstall old version...

What is the recommended approach?

Hi, an in place upgrade should be fine. Details on how to upgrade are available at and specific notes on 3.5.9 are available at

One more detail:

I have a evaluation version installed (3.5.6) and I want to change this to a test version (3.5.9).

I have generated a new license key for this.

In the first link you provided it refers to download the exe version of the Windows installer

Upgrading Confluence on Windows

  1. Download theConfluence 'Windows Installer'(.exe) file (for the new version of Confluence) from theConfluence Download Center.

This link gives me only the evaluation exe file...

Can I use this file and change the license key afterwards?

Yes, you can use use that version and change the license afterwards. All of the binaries Atlassian provide are the same it's just the license that determines the number of users, eval, etc. Hope that helps.

Well, that exe-file does not seem to recognize any existing installs. It will only create a new install.

Any tips ?

Sorry, that first link would have probably taken you to the latest version of Confluence (4.1) rather than version 3.5.9. Version 3.5.9 is available from the download archive and I'm guessing you'll need the 3.5.9 Standlaone (ZIP archive) which is available at , but if you're running clustered and/or EAR/WAR then download the relevant clustered/EAR/WAR version instead.

You can still upgrade in place, but as 3.5.9 doesn't come with an automated installer you'll need to follow the instructions at, or if you're upgrading an EAR/WAR version follow the instructions at

Hope that helps,
