# Replace Categories

You can use the `CategoryReplace` action to replace a category with another category. For example:

    action=CategoryReplace&FromCategory=123456789012345&ToCategory=98765432109876&BuildNow=True

In this example, the IDOL Category component replaces the `98765432109876` category with the `123456789012345` category. The `BuildNow` parameter instructs Category to build the categories immediately, so that they become active. You can also activate the category at a later point by using the `CategoryBuild` action.
