Creating the Import File: From UBB.classic Important: The export feature from UBB.classic is only supported in UBB.classic Version 6.7.0 and version 6.7.2 or higher. Version 6.7.1 contains a bug that prevents the export option from working as expected. To perform the export, choose the Import/Export menu option in the UBB.classic control panel, and follow the prompts. This will create the necessary CSV files in your UBB.classic server’s NonCGI/importexport directory.
The contents of this directory must then be downloaded and uploaded to your UBB.threads/imports directory. Be sure to transfer the files in ASCII mode.[/]
I guess you would then go to your Control Panel in UBB.threads and follow the
Import Data link which is found on the left navbar under
Content Management.
