How to Move Joomla Posts to WordPress

1. Log in to your WordPress admin control panel. From the large menu bar on the left, click 'Plugins,' and then 'Add New.' Type 'Joomla/Mambo To WordPress Migrator' into the search box, and then click the 'Search Plugins' button. When the search has completed, find 'Joomla/Mambo To WordPress Migrator' in the results list, click 'Install Now,' wait for the plugin to install, and then click the 'Activate' link when prompted.
2. Sign in to the root FTP account. Navigate to your Joomla installation, and then copy the folder called 'Images' to your computer. Then navigate to your WordPress installation, and go to 'wp-content' ' 'Plugins' ' 'Joomla-to-wordpress-migrator.' Upload the 'Images' folder you just downloaded to this location, selecting the option to overwrite any files if prompted by the FTP program.

3. Go back to your WordPress admin control panel. From the menu on the left, click 'Joomla2WP,' and then 'Settings.' You will see a number of text fields. Enter the user name and password for the MySQL server in the relevant boxes near the top. Underneath this are fields for your WordPress and Joomla user names and passwords -- fill these in too. Finally, a number of fields ask for certain URLs -- fill these out to give the plugin the locations of your Joomla and Wordpress sites, and the image folders for each. For Joomla, this is usually yoursitelocation/images. For WordPress, this is usually yoursitelocation/wp-content/uploads.
4. Click 'Migration' from the main menu on the left. Click the 'Start Migration' button. Depending on the size of your site, this process might take a few minutes. When it is done, click the 'Change URLs' button. This changes the URLs in your posts so that they point to posts an images on the WordPress installation instead of the Joomla site. Again, this may take a little while if you have a lot of posts.
