Traditional approaches to MongoDB to Cosmos DB migrations
don't work well for production use cases
X
Dump-restore is slow and fragile -hours to days and requires prolonged downtime.
X
Azure Data Factory and 3rd party ETL tools not optimized for migrations, have learning curve and no Private Link support.
X
Kafka-based DIY solutions require weeks to months of set up, orchestration and custom code.
Dsync accelerates timelines and reduces risks for migrations
from MongoDB to Cosmos DB vCore
with one single command
dsync -s $MONGO -d $COSMOS
✅ Runs anywhere you like. On a VM, on your laptop, etc.
✅ Lightweight, works out-of-the box. No SaaS or Kafka.
✅ Resumable at any stage. Initial sync or CDC.
✅ Secure and verifyable. Your data stays with you.
01
Parallelized and resumable Initial Data Copy
➤ 10x faster than other tools on the market or DIY scripts
➤ Dsync is secure and doesn't persist any transient data
➤ Easily track progress using Command-Line Interface or Web UI
02
Real-time incremental sync and CDC
➤ Optimized performance of 1000+ ops/sec for active workloads
➤ Automatically resumes from the last checkpoint on restart
➤ Seamless transition from Initial Data Copy
03
Cutover
➤ No downtime out-of-the-box
➤ Embedded data integrity checks
➤ Simple backout by reversing direction
