Upgrade 3.4.2 to 5.X

Hi,

I currently have an confluence 3.4.2 installation that I'd like to upgrade to the latest 5.X version. It is currently setup using an MySQL database.

Could I please get a top down overview of the steps I'll need to take to upgrade? Should I upgrade 3->4->5 etc.

My home directory is not terribly big, 200Mb mostly attachments.

Thanks

Hey Eli,

The recommended upgrade path for you would be: 3.4.2 > 3.5.13 > 4.3.7 >5.1.3

3.5.13 first because there is a critical upgrade task in 3.5.x to upgrade your user management framework, which is known to fail quite often, especially if you have external usermanagement such as JIRA, Crowd or LDAP.

4.3.7 because of the change in content storage format (wiki markup to xhtml), which will trigger the wikiToXhtml migration task and change your storage format to xhtml. This is known to break pages with certain third party plugins that are no longer compatible with 4.x and above.

Before the upgrade, make sure to take backups of your Confluence Home Directory, and Confluence Database, and always test the upgrade in a test environment.


All the best!

Thanks I think that is the way to go as you suggest. Still having an issue upgrading to 3.5.13 getting this at the output:

Working through it slowly. Thanks for the advice.

You should go from 3.x to 4.x and from 4.x to 5.x. I would suggest the latest stable release of 4.x and 5.x as the versions to use.

Reading the top notes from Upgrading Confluence would help.
