Migrating to LangSmith

Setup

1. Create a .env file in the project root following the .env.example file

2. Use a Python virtual environment and install dependencies.

python3 -m venv .venv
source .venv/bin/activate
pip install -U pip
pip install -r requirements.txt

Migrating Prompts, Datasets, and Traces

The migration orchestrator prompts you to select which observability framework you want to migrate from.

source .venv/bin/activate
python -u migrate.py

1. Select the desired observability provider to migrate from
2. Confirm migration settings with yes or no to migrate prompts, datasets, and traces.
   • Note: Trace replay is for illustrative purposes on how to convert formats. Migrating your full trace data to LangSmith should be done using bulk export functionality.

Runbooks (Notebooks)

Each provider has a runbook notebook to illustrate how to migrate your existing code to utilize LangSmith.

Each observability provider in this repo has a runbook under its corresponding directory.

• Langfuse runbook: providers/langfuse/runbook.ipynb
• Arize Phoenix runbook: providers/phoenix/runbook.ipynb

Usage:

1. Open the runbook in your IDE or using jupyter notebook in the root directory.
2. Review sections for prompts, datasets, and traces.
3. Execute cells to inspect transformations and payloads.
