# Migration

> Learn how to migrate Unstructured Python SDK code away from deprecated ConnectorConfigInput and ConnectorType classes to current alternatives.

This page contains information about how to migrate from previous versions of the
[Unstructured Pipelines operations](/api-reference/workflow/overview).

## ConnectorConfigInput and ConnectorType classes are deprecated

**Applies to**: The [Unstructured Python SDK](/overview-python-sdk) only.

**Issue**: Referencing classes that end in `ConnectorConfigInput` such as `S3SourceConnectorConfigInput`
and `S3DestinationConnectorConfigInput`, and referencing classes that end in `ConnectorType` such as
`S3SourceConnectorType` and `S3DestinationConnectorType`, produce warnings at design time and errors at run time.

**Cause**: The preceding classes have been deprecated and are no longer supported.

**Solution**:

* Remove references to classes that end in `ConnectorConfigInput` from your code. Replace these references with a
  dictionary. This dictionary must contain the same fields as the
  class that you removed, with dictionary key/value pairs instead of object parameter/argument pairs.
* Remove references to classes that end in `ConnectorType` from your code. Replace these references with a string reference instead. This
  string corresponds to Unstructured's programmatic identifier for the connector type, for example `s3` for Amazon S3.

For example, the following code template shows the deprecated approach for programmatically creating an S3 source connector.

```python Python SDK theme={null}
# Deprecated code example. Do not use.
import os

from unstructured_client import UnstructuredClient
from unstructured_client.models.operations import CreateSourceRequest
# The SourceConnectorType and S3SourceConnectorConfigInput classes are deprecated.
from unstructured_client.models.shared import (
    CreateSourceConnector,
    SourceConnectorType,         # <- Remove. Deprecated.
    S3SourceConnectorConfigInput # <- Remove. Deprecated.
)

with UnstructuredClient(api_key_auth=os.getenv("UNSTRUCTURED_API_KEY")) as client:
    response = client.sources.create_source(
        request=CreateSourceRequest(
            create_source_connector=CreateSourceConnector(
                name="<name>",
                type=SourceConnectorType.S3, # <- Replace SourceConnectorType.S3 with a string reference to "s3".
                # Replace S3SourceConnectorConfigInput with a typed dictionary.
                config=S3SourceConnectorConfigInput(
                    # For anonymous authentication:
                    anonymous=True,

                    # For AWS access key ID with AWS secret access key authentication:
                    key="<key>", 
                    secret="<secret>", 

                    # For AWS STS token authentication:
                    token="<token>", 
                    key="<key>", 
                    secret="<secret>", 

                    remote_url="<remote_url>",
                    endpoint_url="<endpoint-url>", 
                    recursive=<True|False>
                )
            )
        )
    )

    print(response.source_connector_information)
```

To address this issue, use the following code template instead, which removes the
`SourceConnectorType` and `S3SourceConnectorConfigInput` class references and replaces them
with the correct substitutions.

```python Python SDK theme={null}
import os

from unstructured_client import UnstructuredClient
from unstructured_client.models.operations import CreateSourceRequest
from unstructured_client.models.shared import CreateSourceConnector

with UnstructuredClient(api_key_auth=os.getenv("UNSTRUCTURED_API_KEY")) as client:
    response = client.sources.create_source(
        request=CreateSourceRequest(
            create_source_connector=CreateSourceConnector(
                name="<name>",
                type="s3",
                config={
                    # For anonymous authentication:
                    "anonymous": True,

                    # For AWS access key ID with AWS secret access key authentication:
                    "key": "<key>", 
                    "secret": "<secret>", 

                    # For AWS STS token authentication:
                    "token": "<token>", 
                    "key": "<key>", 
                    "secret": "<secret>", 

                    "remote_url": "<remote_url>",
                    "endpoint_url": "<endpoint-url>", 
                    "recursive": <True|False>
                }
            )
        )
    )

    print(response.source_connector_information)
```
