🔄 What Is Data Migration?

Data migration is the process of transferring data from one system, storage, or format to another. This could involve moving from on-premises to cloud, upgrading databases, or consolidating systems.

🧠 Why a Strategic Approach to Data Migration Matters

Without a defined migration plan, organizations face:

❌ Unexpected downtime

❌ Data integrity issues

❌ Compliance and security violations

❌ Loss of business continuity

A well-structured migration strategy ensures that your data moves safely, completely, and with minimal disruption.

🧭 Types of Data Migration

🛠️ Common Data Migration Strategies

1. Big Bang Migration

Approach: All data is transferred in one go, during a fixed time window.

Pros:
✔️ Simple planning
✔️ Short timeline

Cons:
❌ High downtime risk
❌ Difficult to rollback
❌ Not ideal for mission-critical systems

2. Trickle Migration (Phased Migration)

Approach: Data is moved in stages while both systems run in parallel.

Pros:
✔️ Minimal disruption
✔️ Easier testing and validation
✔️ Better risk management

Cons:
❌ More complex architecture
❌ Longer timeline

3. Hybrid Migration

Approach: Combines both big bang and phased approaches.

Use Case: Best when migrating large datasets but needing certain services live throughout the process.
