If you are starting from local source code, modify the environment variable in the `.env` file to the vector database you want to migrate to. For example: ``` VECTOR_STORE=qdrant ```` 2. If you are starting from `docker compose`, modify the environment variable in the `docker-compose.yaml` file to the vector database you want to migrate to, both api and worker are all needed. For example: ``` # The type of vector store to use. Supported values are `weaviate`, `qdrant`, `milvus`. VECTOR_STORE: qdrant ``` 4. run the below command in your terminal or docker container ``` flask vdb-migrarte ``` ## Update Guide ### Deploying with Docker Compose: 1. Get the latest code from the main branch: ```shell git checkout main git pull origin main ``` 2. Go to the next step and update to the latest image: ```shell cd docker docker-compose up -d ``` ### Deploying from Source Code: 1. Stop API server, Worker and Web frontend Server. 2. Get the latest code from the main branch: ```shell git checkout main git pull origin main ``` 3. Then, let's run the migration script: ```shell cd api flask db upgrade ``` **Note**: To use TTS, `ffmpeg` installation is required on servers running Dify API from source. More details can be found in our [FAQ](https://docs.dify.ai/getting-started/install-self-hosted/install-faq#id-14.-what-to-do-if-this-error-occurs-in-text-to-speech). 4. Finally, run API server, Worker and Web frontend Server again. ## What's Changed * Windows local deployment switch "tool“ interface failed by @kukuze in https://github.com/langgenius/dify/pull/2483 *
