Can I pick category articles are migrated into?

The plugin keeps the same categories as Joomla.
You can import the articles to WordPress first using the plugin and then assign the specific category.

Thank you for clarifying. I’m going to give it a try soon.

Edit: Nevermind, I got it working, had to add the IP address, not the host name for remote access list.

Unfortunately, I can’t get it to connect to the database, and I’ve filled out everything correctly to my knowledge. I even added my hostname to remote mysql access host list on the other web host. Any idea why it won’t connect?
