How to upgrade from 6.15.7 to 6.4.3


I need to upgrade my Confluence server instance from version 6.15.7 to 6.4.3. The 'Upgrade to' dropdown list in 'Plan your upgrade' section does not list this version.

Is it possible at all to upgrade Confluence to a specific version?

Hello @Jeny Amatya ,


6.15.7 is somehow the latest one compared with 6.4.3.

Hi @Jeny Amatya ,

I didn't done any downgrade previously. if you have the test instance. You may try as in the below link. 

But Please raise a ticket to Support , before downgrading and enquire about security concerns about 6.4.3
