custom processors or entity providers, read on. Otherwise, you should be able to
just delete that file at this point.
#### Amazon Web Services
`AwsEksClusterProcessor` and `AwsOrganizationCloudAccountProcessor` have not yet been migrated to the new backend system.
See [Other Catalog Extensions](#other-catalog-extensions) for how to use these in the new backend system.
For `AwsS3DiscoveryProcessor`, first migrate to `AwsS3EntityProvider`.
To migrate `AwsS3EntityProvider` to the new backend system, add a reference to the `@backstage/plugin-catalog-backend-module-aws` module.
```ts title="packages/backend/src/index.ts"
backend.add(import('@backstage/plugin-catalog-backend/alpha'));
/* highlight-add-start */
backend.add(import('@backstage/plugin-catalog-backend-module-aws/alpha'));
/* highlight-add-end */
```
If you were providing a `schedule` in code, this now needs to be set via configuration.
All other AWS configuration in `app-config.yaml` remains the same.
```yaml title="app-config.yaml"
catalog:
providers:
awsS3:
yourProviderId:
# ...
/* highlight-add-start */
schedule:
frequency: PT1H
timeout: PT50M
/* highlight-add-end */
```
#### Azure DevOps
For `AzureDevOpsDiscoveryProcessor`, first migrate to `AzureDevOpsEntityProvider`.
To migrate `AzureDevOpsEntityProvider` to the new backend system, add a reference to the `@backstage/plugin-catalog-backend-module-azure` module.
```ts title="packages/backend/src/index.ts"

#### Open API
`InternalOpenApiDocumentationProvider` has not yet been migrated to the new backend system.
See [Other Catalog Extensions](#other-catalog-extensions) for how to use this in the new backend system.
#### Bitbucket
For `BitbucketDiscoveryProcessor`, migrate to `BitbucketCloudEntityProvider` or `BitbucketServerEntityProvider`
To migrate `BitbucketCloudEntityProvider` to the new backend system, add a reference to the `@backstage/plugin-catalog-backend-module-bitbucket-cloud` module.
```ts title="packages/backend/src/index.ts"
backend.add(import('@backstage/plugin-catalog-backend/alpha'));
