Zilliz Migration Service vs. Vector Transport Service (VTS)

Vector Transport Service (VTS) is our open-source migration tool built on Apache Seatunnel. It offers nearly identical capabilities to the Zilliz Migration Service—including support for all major data sources—but requires self-deployment and management. Zilliz Migration Service, built on VTS, provides a fully managed, out-of-the-box experience with additional enterprise support.

Frequently asked questions

1. What is Zilliz Migration Service, and how does it work?
Zilliz Migration Service is a fully managed migration tool designed specifically for unstructured and vector data. It streamlines the entire process—automating extraction, transformation, and loading—from various data sources into Zilliz Cloud. This means you can migrate your data seamlessly with minimal manual intervention and downtime.
2. Which data sources are supported by Zilliz Migration Service?
The service supports a broad range of data sources, including vector databases like Milvus, Pinecone, Qdrant, as well as search engines like Elasticsearch, and relational databases such as PostgreSQL. It works with both cloud environments (AWS, Azure, GCP) and on-premises systems.
3. How does Zilliz Migration Service ensure zero downtime during migration?
By using the zero downtime migration mode, the service creates an initial data snapshot and then continuously synchronizes any subsequent changes. This approach allows your applications to keep running on the source database while the migration happens in the background, ensuring a near-zero-downtime transition.
4. What prerequisites must be met to use Zilliz Migration Service?
To get started, your source database needs to be accessible over the network (typically requiring public internet access) so that our service can connect and extract data. You also need to create a cluster within Zilliz Cloud as the destination. Additionally, you may need to perform some minimal configuration for schema mapping and data transformation based on your specific setup. See our documentation for more details.
5. How do I get started with Zilliz Migration Service?
Getting started is easy! Simply visit our Zilliz Migration Service portal for access to detailed documentation and step-by-step guides. These resources will walk you through configuring your source and destination systems, setting up migration parameters, and monitoring the process from start to finish.
6. What is the difference between Zilliz Migration Service and Vector Transport Service (VTS)?
While both tools offer similar migration capabilities and support all major data sources, Zilliz Migration Service is a fully managed, out-of-the-box solution with enterprise support. In contrast, Vector Transport Service (VTS) is an open-source tool that requires you to deploy and manage it on your own infrastructure, making it ideal for users with existing technical expertise and resources.
7. Can I migrate data from both cloud and on-premises environments?
Yes! Zilliz Migration Service is designed to handle migrations from both cloud-based platforms (such as AWS, Azure, and GCP) and on-premises systems, providing you with the flexibility to work within your existing infrastructure.
8. How does the service handle data transformation and schema mapping?
The service includes built-in capabilities to manage data transformation and schema mapping automatically. It adjusts data formats and structures during migration to ensure compatibility with your destination system, reducing the risk of errors and streamlining the overall process.
9. Is there any cost associated with using Zilliz Migration Service?
Zilliz Migration Service is offered as a free, fully managed solution.
10. What support and documentation are available if I encounter issues during migration?
We provide comprehensive documentation—including user guides, FAQs, and troubleshooting tips—on our website. Additionally, our dedicated support team is available to assist you with any challenges you might face during the migration process, ensuring a smooth experience.
