DO NOT USE PORTER FOR UPGRADING VANILLA 2. It is for migrating from other incompatible forum platforms.
The official release is a single file. View the official documentation for important usage notes. This repository is for developers.
You can alternatively upload this entire folder to your web server if you want to use the latest bleeding-edge version or develop your own format. To do so, access it via index.php and ignore vanilla2export.php (the compiled version) entirely.
To create a new export format, add a new file in the format "class.yournewformatname.php" which will automatically be added to the dropdown list of export options. Copy one of the existing classes as an example / starting place. We recommend using a simpler one for this like SMF.
Porter can run via the command line. Execute the index.php file with the --help flag for a full list of options. For developers with very large databases or ones still in production, we recommend running your export from the command line on your localhost environment with a copy of the database.
