I have saved my configuration from 6.7 and installed all apps on 7.2 then tried to upload my backup from 6.7 to restore to 7.2, I received the error "The uploaded file exceeds the maximum allowed size." when doing so. I'm not sure how large the file should normally be, but mine is about 4.5MB. Has anyone else seen this? Is the upgrade process working from 6 to 7 yet? From what I gather the Zarafa migration is still a manual process, but documented.
