Traditional approaches for MongoDB migrations
don't work well for migrations from Cosmos DB
X
Dump-restore takes hours to days and requires prolonged downtime.
Atlas Live Migrate and other MongoDB tools don't support Cosmos DB.
X
Kafka-based DIY solutions require weeks to months of set up, orchestration and custom code.
X
3rd party ETL tools don't support Cosmos DB as a source and not optimized for migrations.
Dsync accelerates timelines and reduces risks for migrations
from Cosmos DB to MongoDB Atlas
with one single command
dsync -s $COSMOS -d $ATLAS
✅ 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
