+# LangGraph Platform Migration Guide
+
+We have [recently announced](https://blog.langchain.dev/langgraph-platform-announce/) LangGraph Platform, a ***significantly*** enhanced solution for deploying agentic applications at scale.
+
+LangGraph Platform incorporates [key design patterns and capabilities](https://langchain-ai.github.io/langgraph/concepts/langgraph_platform/#option-2-leveraging-langgraph-platform-for-complex-deployments) essential for production-level deployment of large language model (LLM) applications.
+
+In contrast to LangServe, LangGraph Platform provides comprehensive, out-of-the-box support for [persistence](https://langchain-ai.github.io/langgraph/concepts/application_structure/), [memory](https://langchain-ai.github.io/langgraph/concepts/assistants/), [double-texting handling](https://langchain-ai.github.io/langgraph/concepts/double_texting/), [human-in-the-loop workflows](https://langchain-ai.github.io/langgraph/concepts/assistants/), [cron job scheduling](https://langchain-ai.github.io/langgraph/concepts/langgraph_server/#cron-jobs), [webhooks](https://langchain-ai.github.io/langgraph/concepts/langgraph_server/#webhooks), high-load management, advanced streaming, support for long-running tasks, background task processing, and much more.
+
+The LangGraph Platform ecosystem includes the following components:
+
+- [LangGraph Server](https://langchain-ai.github.io/langgraph/concepts/langgraph_server/): Provides an [Assistants API](https://langchain-ai.github.io/langgraph/cloud/reference/api/api_ref.html) for LLM applications (graphs) built with [LangGraph](https://langchain-ai.github.io/langgraph/). Available in both Python and JavaScript/TypeScript.
+- [LangGraph Studio](https://langchain-ai.github.io/langgraph/concepts/langgraph_studio/): A specialized IDE for real-time visualization, debugging, and interaction via a graphical interface. Available as a web application or macOS desktop app, it's a substantial improvement over LangServe's playground.
+- [SDK](https://langchain-ai.github.io/langgraph/concepts/sdk/): Enables programmatic interaction with the server, available in Python and JavaScript/TypeScript.
+- [RemoteGraph](https://langchain-ai.github.io/langgraph/how-tos/use-remote-graph/): Allows interaction with a remote graph as if it were running locally, serving as LangGraph's equivalent to LangServe's RemoteRunnable. Available in both Python and JavaScript/TypeScript.
+ 
+## Context 
+
+LangServe was built as a deployment solution for LangChain Runnables created using the [LangChain Expression Language (LCEL)](https://python.langchain.com/docs/concepts/lcel). In LangServe, the LCEL was the orchestration layer that managed the execution of the Runnable.
+
+[LangGraph](https://langchain-ai.github.io/langgraph/) is an open source library created by the LangChain team that provides a more flexible orchestration layer that's better suited for creating more complex LLM applications. LangGraph Platform
+is the deployment solution for LangGraph applications.
+
+## LangServe Support
+
+We recommend using LangGraph Platform rather than LangServe for new projects.
+
+We will continue to accept bug fixes for LangServe from the community; however, we will not be accepting new feature contributions.
+
+## Migration
+
+If you would like to migrate an existing LangServe application to LangGraph Platform, you have two options:
+
+1. You can wrap the existing `Runnable` that you expose in the LangServe application via `add_routes` in a `LangGraph` node. This is the quickest way to migrate your application to LangGraph Platform.
+2. You can do a larger refactor to break up the existing LCEL into appropriate `LangGraph` nodes. This is recommended if you want to take advantage of more advanced features in LangGraph Platform.
+
+### Option 1: Wrap Runnable in LangGraph Node
+
+This option is the quickest way to migrate your application to LangGraph Platform. You can wrap the existing `Runnable` that you expose in the LangServe application via `add_routes` in a `LangGraph` node.
+
+
+Original LangServe code:
+
+```python
+from langserve import add_routes
+
+app = FastAPI()
+
+# Some input schema
+class Input(BaseModel):
+    input: str
+    foo: Optional[str]
+
+# Some output schema
+class Output(BaseModel):
+    output: Any
+    
+    
+runnable = .... # Your existing Runnable
+runnable_with_types = runnable.with_types(input_type=Input, output_type=Output)
+
+# Adds routes to the app for using the chain under:
+add_routes(
+    app,
+    runnable_with_types,
+)
+```
+
+Migrated LangGraph Platform code:
+
+```python
+
+@dataclass
+class InputState: # Equivalent to Input in the original code
+    """Defines the input state, representing a narrower interface to the outside world.
+
+    This class is used to define the initial state and structure of incoming data.
+    See: https://langchain-ai.github.io/langgraph/concepts/low_level/#state
+    for more information.
+    """
+
+    input: str
+    foo: Optional[str] = None
+
+
+@dataclass
+class OutputState: # Equivalent to Output in the original code
+    """Defines the output state, representing a narrower interface to the outside world.
+    
+    https://langchain-ai.github.io/langgraph/concepts/low_level/#state
+    """
+    output: Any
+
+@dataclass
+class SharedState:
+    """The full graph state.
+    
+    https://langchain-ai.github.io/langgraph/concepts/low_level/#state
+    """
+    input: str
+    foo: Optional[str] = None
+    output: Any
+    
+runnable = ... # Same code as before
+
+async def my_node(state: InputState, config: RunnableConfig) -> OutputState:
+    """Each node does work."""
+    return await runnable.ainvoke({"input": state.input, "foo": state.foo})
+
+
+# Define a new graph
+builder = StateGraph(
+    SharedState, config_schema=Configuration, input=InputState, output=OutputState
+)
+
+# Add the node to the graph
+builder.add_node("my_node", my_node)
+
+# Set the entrypoint as `call_model`
+builder.add_edge("__start__", "my_node")
+
+# Compile the workflow into an executable graph
+graph = builder.compile()
+graph.name = "New Graph"  # This defines the custom name in LangSmith
+```
+
+### 2. Refactor LCEL into LangGraph Nodes
+
+This option is recommended if you want to take advantage of more advanced features in LangGraph Platform.
+
+#### Memory (alternative to `RunnableWithMessageHistory`)
+
+For example, LangGraph comes with built-in persistence that is more general than LangChain's `RunnableWithMessageHistory`.
+
+Please refer to the guide on [upgrading to LangGraph memory](https://python.langchain.com/docs/versions/migrating_memory/) for more details.
+
+#### Agents
+
+If you're relying on legacy LangChain agents, you can migrate them into the pre-built
+LangGraph agents. Please refer to the guide on [migrating agents](https://python.langchain.com/docs/how_to/migrate_agent/) for more details.
+
+#### Custom Chains
+
+If you created a custom chain and used LCEL to orchestrate it, you will usually be able to refactor it into a LangGraph without too much difficulty.
+
+There isn't a one-size-fits-all guide for this, but generally speaking, consider creating
+a separate node for any long-running step in your LCEL chain or any step that you would
+want to be able to monitor or debug separately.
+
+For example, if you have a simple Retrieval Augmented Generation (RAG) pipeline, you might have a node for the retrieval step and a node for the generation step.
+
+Original LCEL code:
+
+```python
+...
+rag_chain = (
+    {"context": retriever | format_docs, "question": RunnablePassthrough()}
+    | prompt
+    | llm
+    | StrOutputParser()
+)
+rag_chain.with_types(input_type=Input, output_type=Output)
+```
+
+Using LangGraph for the same pipeline:
+
+
+```python
+
+@dataclass
+class InputState: # Equivalent to Input in the original code
+    """Input question from the user."""
+    question: str
+   
+@dataclass 
+class OutputState: # Equivalent to Output in the original code
+    """The output from the graph."""
+    answer: str
+
+@dataclass 
+class SharedState:
+    question: str
+    docs: List[str]
+    response: str
+   
+async def retriever_node(state: InputState) -> SharedState:
+    """Rettrieve documents based on the user's question."""
+    documents = await retriever.ainvoke({"context": state.question})
+    return {
+        "docs": documents
+    }
+
+async def generator_node(state: SharedState) -> OutputState:
+    """Generate an answer using an LLM based on the retrieved documents and question."""
+    context = " -- DOCUMENT -- ".join(state.docs)
+    prompt = [
+        SystemMessage(
+            content=(
+                "Answer the user's question based on the list of documents "
+                "that were retrieved. Here are the documents: \n\n"
+                f"{context}"
+            )
+        ),
+        HumanMessage(content=state.question),
+    ]
+    ai_message = await llm.ainvoke(prompt)
+    return {"answer": ai_message.content}
+    
+# Define a new graph
+builder = StateGraph(
+    SharedState, config_schema=Configuration, input=InputState, output=OutputState
+)
+builder.add_node("retriever", retriever_node)
+builder.add_node("generator", generator_node)
+builder.add_edge("__start__", "retriever")
+builder.add_edge("retriever", "generator")
+graph = builder.compile()
+graph.name = "RAG Graph"
+```
+
+Please see the [LangGraph tutorials](https://langchain-ai.github.io/langgraph/tutorials/)
+for tutorials and examples that will help you get started with LangGraph
+and LangGraph Platform.

+## ⚠️ LangGraph Compatibility
+
+LangServe is designed to primarily deploy simple Runnables and work with well-known primitives in langchain-core.
+
+If you need a deployment option for LangGraph, you should instead be looking at [LangGraph Cloud (beta)](https://langchain-ai.github.io/langgraph/cloud/) which will
+be better suited for deploying LangGraph applications.
+

@@ -80,39 +86,64 @@ Use the `LangChain` CLI to bootstrap a `LangServe` project quickly.
 To use the langchain CLI make sure that you have a recent version of `langchain-cli`
 installed. You can install it with `pip install -U langchain-cli`.
 
+## Setup
+
+**Note**: We use `poetry` for dependency management. Please follow poetry [doc](https://python-poetry.org/docs/) to learn more about it.
+
+### 1. Create new app using langchain cli command
+
 ```sh
-langchain app new ../path/to/directory
+langchain app new my-app
+```
+
+### 2. Define the runnable in add_routes. Go to server.py and edit
+
+```sh
+add_routes(app. NotImplemented)
+```
+
+### 3. Use `poetry` to add 3rd party packages (e.g., langchain-openai, langchain-anthropic, langchain-mistral, etc).
+
+```sh
+poetry add [package-name] // e.g `poetry add langchain-openai`
+```
+
+### 4. Set up relevant env variables. For example,
+
+```sh
+export OPENAI_API_KEY="sk-..."
+```
+
+### 5. Serve your app
+
+```sh
+poetry run langchain serve --port=8100
 ```
