# Replace All Categories
> Clear every category from the selected products and assign new ones in a single action. A clean-slate recategorization.
Clear every existing category from the selected products and assign new ones in one action. This is a clean-slate approach. Use it when you want to fully recategorize products.
This action removes **all existing categories** before assigning the new ones. To add categories without removing what's already there, use [Assign to Categories](/en/essentials/bulk-editing/assign-categories) instead.
## Replace all categories
Check the products you want to recategorize, or use filters and select all matching results.
Click **Bulk Edit**, then search for "Replace All Categories" or find it under **Categories & Organization**.
Use the category tree to choose the new categories. Parent categories are auto-selected by default.
Review the warning about existing categories being removed, then click **Apply**.
## Configuration options
| Option | Description | Default |
| --------------------------------- | --------------------------------------------------------------- | ------- |
| **Categories** | The new categories to assign (replaces all existing) | No |
| **Auto-select parent categories** | Automatically include parent categories when you select a child | On |
## Tips
* This is the fastest way to move products from one category structure to another. There's no need to remove old categories first.
* Use this when migrating to a new category tree or restructuring your catalog.
* Test on a small batch first to confirm the new assignments look correct before applying to your full selection.
