What is the timeline for a MongoDB 4.4 to 7.0 upgrade?

A typical MongoDB 4.4 to 7.0 upgrade takes 2-4 weeks including assessment (1 week), preparation and testing (1-2 weeks), and production migration (1-2 days). The exact timeline depends on database size, complexity, and application dependencies.

How is zero downtime guaranteed during migration?

We use advanced replica set techniques including primary-secondary replication, read preference routing, and gradual cutover strategies. This allows your application to continue serving requests while data is synchronized to the new environment, with typical downtime under 3 minutes during final cutover.

Which migration tools do you use for MongoDB?

We use industry-leading tools including MongoDB Atlas Live Migration, mongodump/mongorestore, MongoDB Database Tools, Change Streams, Ops Manager, and custom migration scripts. Tool selection depends on your specific migration scenario and requirements.

How do you ensure data integrity post-migration?

We perform comprehensive data validation including document validation, collection count verification, index consistency checks, and referential integrity validation. All data is verified before, during, and after migration with automated validation scripts.

Can you handle large (TB-scale) MongoDB databases?

Yes, we have extensive experience migrating TB-scale MongoDB databases. We use optimized migration strategies including parallel data transfer, incremental synchronization, and sharding optimization to handle large datasets efficiently while maintaining zero downtime.

What happens if something goes wrong during migration?

We have comprehensive rollback procedures including automated rollback scripts, point-in-time recovery, and configuration backups. If any issues arise, we can immediately roll back to the original environment with zero data loss.

Do you maintain compliance during migration?

Yes, we ensure all compliance requirements (GDPR, HIPAA, SOX) are maintained throughout the migration process with compliance mapping, audit trail maintenance, security controls, and comprehensive documentation.

Migration in flight — sound familiar?

▸ Oplog wrapping mid-migration — Source cluster oplog rolling past the migration cursor; mongosync can't resume after a transient network blip and you're forced into a full re-sync.
▸ mongosync stalled, no error — Status endpoint returns running but nothing's moving; restart loses replication position, dual-write window has to be extended again.
▸ Atlas → DocumentDB feature gap — Multi-document transactions, change-stream resume tokens, and aggregation pipeline operators that worked in Atlas silently no-op on DocumentDB.
