Problem:
What is the Layouts Migration Plugin and how to use it?

Solution:
This utility plugin will help you migrate layouts that you created for single pages, to the new Content Layouts.

You only need this plugin if you built a site with Layouts 1.8.x or earlier and you are updating to the current version of Layouts plugin.

This is the "how to":
https://toolset.com/documentation/user-guides/how-to-use-the-toolset-layouts-migration-plugin/

It will remove the existing Layouts and add Content Layouts instead, to each single Post or Page.

Your design (made with Layouts) is still applied to the Contents, but not anymore present in Toolset > Layouts, instead, you will see it in any_post_type Where the Layouts were applied to, when you edit them, in the Edit Screen of the Single Post.
When you edit the Contents, do you see an Orange Button that says "Content Layout Editor."
When you click on that you should be able to edit exactly what you designed in Layouts previously.

The new Content Layouts are NOT exportable like the old Template Layouts, and they below each to a post, not each to several Posts.
