Updating Custom Theme (Section type 'custom-categories' does not refer to an existing section file)

I have a customized theme based on Dawn version 6.02. Everything has been working fine, but I am noticing some glitchy stuff and so I am attempting to upgrade to Version 11.0. I have successfully copied my Settings_Data.json file to the updated Dawn Version but I am getting the following error when trying to copy my index.json file. Any suggestions on how to fix this would be appreciated.

Hi, also getting this issue. Any responses available?

Hey @raniatpopkorn!

The issue that you’re facing in the index.json file is that, you’re attempting to refer the section in the new updated theme, that actually not existing. Let me explain what does it means.

Let say, you are using the Shopify Dawn theme version 6.0.1 but now you want to update it. Let say the updated version is 15.0.1. So, that’s the twist comes when the theme updates.

When the theme updates then the theme developer also change the name of the sections. That’s meant that if in the 6.0.1 the section name id image with text then possibility they change to image with content in the new updated theme.

That say, you need to find the correct names and then input the correct names there.

Hi @raniatpopkorn @RubberDuckie
Check the theme change log that you want to update and see if they have shared a list of sections that have changed. You can then update the name in your code.
