Hello

I have a question related to the edition of categories.

In my community, we start with a category, and a sub-category.

We have:  
`forum.com/c/category-main` → slug: `#category-main`  
`forum.com/c/category-main/secondary` → slug: `#category-main:secondary`

Everything works spectacular.

That is, there are debates where the main category is mentioned: `#category-main`  
And there are debates where the sub-category is mentioned like this: `#category-main:secondary`

**Now, the subcategory has grown and wants to be independent.**  
I know I could edit it, and put it as main.

My doubt about it is about the messages that mention the subcategory that would now be independent. Are they automatically changed or is some type of redirection activated?

I refer to the discussions where it is mentioned: `#category-main:secondary` should now become `#secondary` and redirect to `forum.com/c/secondary` ❓

Will it be like that?

If you rename a category a permalink is created to redirect the old url to the new one.
