The up procedure is because phpmyadmin get errors if you simply create the upload folder, edit the config file than try to import using the web interface of phpmyadmin
webuzo team told to me this:
You can change the PHPmyadmin import file size with the following steps:
Increase SQL import file size in PHPmyadmin:
You need to change the values of the following variables in /usr/local/emps/etc/php.ini binary file:
upload_max_filesize
post_max_size
Once done, restart webuzo service by executing the following command as root:
service webuzo restart
than try to import from the web interface of phpmyadmin.
I never tried this as the solution in my first post works well and is really fast.. however is good to have more information as possibile.
