Data Migration Calculator
Plan your data migration project. Estimate time, resources, and potential downtime for a smooth transition.
Migration Types
Online Migration
Data is migrated while systems remain operational. Minimal downtime but slower migration.
Offline Migration
Systems are taken offline during migration. Faster but requires planned downtime.
Hybrid Migration
Combines online and offline approaches. Balances speed and system availability.
Quick Examples
1TB Online Migration
- Data size: 1000 GB
- Transfer speed: 100 MB/s
- Time: ~2.8 hours
- Downtime: Minimal
2TB Offline Migration
- Data size: 2000 GB
- Transfer speed: 200 MB/s
- Time: ~2.8 hours
- Downtime: Required

Frequently Asked Questions
What's the difference between migration types?
Online migration keeps systems running (minimal downtime), offline requires system shutdown (faster transfer), hybrid combines both approaches for optimal balance.
How accurate are the time estimates?
Estimates are based on theoretical transfer speeds. Real-world factors like network congestion, system load, and data complexity can affect actual times.
What transfer speed should I use?
Use the effective transfer speed of your slowest component (network, source storage, or destination storage). Consider peak vs off-peak performance.
How to minimize migration time?
Use faster storage devices, optimize network connectivity, perform during off-peak hours, and consider incremental or delta sync methods.
When to choose each migration type?
Online for 24/7 systems, offline for fastest transfer when downtime is acceptable, hybrid for large datasets with minimal downtime requirements.
What factors affect migration success?
Data integrity verification, rollback planning, testing procedures, staff training, and comprehensive backup strategies are crucial for success.
