#90 Updating Content from old Version

[Orange Cube]

Hi, we have your system running on an older Version. Now we have to update the content-Manager to the lastest version. So we succesfully installed the latest Version in a new Sub-directory. I tried to import our old Content by copying the content-Folder from the old system to the new Version-Folder. After that the Blog becoms blank - nothing works until i delete the content-folder once again - so how can i transfer the old content to the new System?
