How to upgrade from Sydney free to Sydney Pro


I would like to update my site from the free version of Sydney to Sydney Pro. Is there any documentation on how to do this?

Also, I’m currently using a child theme and wondering what will happen to all the customizations I’ve made to the child theme once I upgrade to the Pro version.

Any help or assistance would be appreciated.

Best Regards,

Hello there,

Check out this documentation.

To sync your child theme width the pro version, edit the header stylesheet (style.css) in child theme folder. It usually contains like this.

    Theme Name: Sydney Child
    Theme URI:
    Author: aThemes
    Author URI:
    Template: sydney
    Version: 1.0
    License: GNU General Public License v2 or later
    License URI:
    Text Domain: sydney

Replace this line:

   Template: sydney 


   Template: sydney-pro-ii

sydney-pro-ii is folder name of the parent theme.


Hi Kharis,

I have another question regarding this. Being that the sydney pro version is a paid theme is it ok to upload this on a test site first? I want to be sure that I won’t have a problem moving it to my live site once all is completed.

Best Regards,

Hello Robbin,

You can use Sydney Pro theme as like any other theme that can be used for any kind of purpose including staging/test site. Once you’re ready to go live, you might want to use duplicator plugin.
