I've been given a space backup from someone elses confluence installation, supposedly version "5.2" which doesn't appear on the downloads page. Attempting to import the space into my 5.2.5 installation results in the error "Restore denied. Your export is too old to be imported in this version of Confluence (Build number 4353 instead of 4208). See Restoring a Space for more information."
None of those build numbers feature on the Confluence Build Information page, though 4353 is referring to my version 5.2.5 installation. Can someone assist in tracking down build 4208 so I can recover this space?
