# The ContentManagerAppState redux is modified

> Source: https://docs.strapi.io/cms/migration/v4-to-v5/breaking-changes/redux-content-manager-app-state

In Strapi 5, the ContentManagerAppState redux store removed RESET_INIT_DATA and GET_INIT_DATA actions, and changed SET_INIT_DATA payload structure to no longer nest attributes within a data object.

In Strapi 5, the redux store for the Content Manager has been changed and some redux actions were removed. Notably, the `useContentManagerInitData` redux state for the Content Manager has been refactored to remove `ModelsContext`. Users might be relying on the original structure in a middleware or subscriber; doing so this will break their application.

This page is part of the [breaking changes database](/cms/migration/v4-to-v5/breaking-changes) and provides information about the breaking change and additional instructions to migrate from Strapi v4 to Strapi 5.

- Is this breaking change automatically handled by a codemod? No

## Breaking change description

**In Strapi v4**

The redux store can fire the following actions:

- `'ContentManager/App/RESET_INIT_DATA’`
- `'ContentManager/App/GET_INIT_DATA’`
- `'ContentManager/App/SET_INIT_DATA’`

The payload nests attributes inside the `data` object. For instance, for the `SET_INIT_DATA` action, the payload is of the following format:

```json
  data: {
    authorizedCollectionTypeLinks: ContentManagerAppState['collectionTypeLinks'];
    authorizedSingleTypeLinks: ContentManagerAppState['singleTypeLinks'];
    components: ContentManagerAppState['components'];
    contentTypeSchemas: ContentManagerAppState['models'];
    fieldSizes: ContentManagerAppState['fieldSizes'];
  };
```

**In Strapi 5**

The redux store no longer fires the following actions:

- `'ContentManager/App/RESET_INIT_DATA’`
- `'ContentManager/App/GET_INIT_DATA’`

The payload data does not nest attributes within a `data` object anymore. For instance, for the `SET_INIT_DATA` action, the payload is of the following format:

```json
{
  authorizedCollectionTypeLinks: ContentManagerAppState['collectionTypeLinks'];
  authorizedSingleTypeLinks: ContentManagerAppState['singleTypeLinks'];
  components: ContentManagerAppState['components'];
  contentTypeSchemas: ContentManagerAppState['models'];
  fieldSizes: ContentManagerAppState['fieldSizes'];
}
```

## Migration

This section regroups useful notes and procedures about the introduced breaking change.

### Manual procedure

The redux store in Strapi 5 continues to fire `'ContentManager/App/SET_INIT_DATA’`, so users should instead listen for this action in their middlewares only.

Additionally, adjustments to your custom code might need to be done based on the new payload format.
