Why Teams Move to Zilliz Cloud
Migration is the first step. Here is what you get once you are on Zilliz Cloud.
Hassle-free and stable
Fully managed Milvus with a 99.95% monthly uptime SLA. Zilliz runs deployment, scaling, upgrades, backups and monitoring, so your team stops babysitting clusters.
Scalability
Scale from millions to tens of billions of vectors, and add capacity as traffic grows without re-architecting.
Lower cost
Tiered storage from $5 per million vectors a month keeps cold data cheap. 123RF cut its search costs by over 50% on Zilliz Cloud.
Search quality
Higher recall under heavy filters on VDBBench, plus BM25 full-text and hybrid search, so results stay relevant as your data grows.
How It Works
- 01
Apply
Tell Zilliz about your current setup: the source database, data size and traffic. Moving from another vector database? Include a recent bill or usage report.
- 02
Workload review
A Zilliz engineer reviews your workload, recommends a cluster and sets your credits.
- 03
Migrate with zero downtime
Move your data with Zilliz Migration Service, a free, fully managed service built on the open-source VTS. Your application keeps serving from the source while data copies and syncs.
- 04
Cut over
Switch traffic to Zilliz Cloud once it has caught up with the source. Your credits apply to your Zilliz Cloud usage.

FAQ
Will my application go down during the migration?
No. Your application keeps serving from the current database while existing data is copied and new writes are synced to Zilliz Cloud. You switch traffic once Zilliz Cloud has caught up. Depending on the source, Zilliz engineers set this up with live sync or with dual writes during the cutover.
Which vector databases qualify?
Pinecone, Weaviate, Qdrant, Elasticsearch, OpenSearch, pgvector, MongoDB Atlas Vector Search, Chroma, LanceDB, turbopuffer, Amazon S3 Vectors and others. If your source isn't listed, apply and a Zilliz engineer will confirm.
How are the credits sized?
For a migration from another vector database, credits are based on what you pay today: Zilliz matches 1–3 months of your current bill for that workload as Zilliz Cloud credits, using the bill or usage report you share. A migration from self-hosted Milvus can receive up to $10,000 in migration credits. Each application is approved case by case.
Does the migration itself cost anything?
No. Zilliz Migration Service is free and fully managed. It is built on VTS, the open-source Vector Transport Service.
Do I need to change my code to move from Milvus?
Zilliz Cloud is fully managed Milvus with the same API and SDKs, so in most cases you point the client at the new endpoint and API key. The Milvus migration guide lists the few differences.
