Forum Version 3.8 and version 4 side by side
 

Okay, I have version 3.8 and version 4 in a subdirectory password protected.

How can I get posts and other database data into my version 4 installation? btw, I don't want a upgrade yet. Just I want the subdirectory (version 4) to have the version 3.8 data.

Regards,
Matt
