Types of Database Migration Strategies:

When it comes to moving your operations to the cloud, understanding the different migration strategies is crucial. These strategies vary based on business needs, resources, and long-term goals. Let’s explore the 6 primary cloud migration strategies in greater detail.

• Rehosting

Also known as ‘lift and shift,’ rehosting involves transferring an exact copy of your current infrastructure, for instance, a Cloud SQL database, to the cloud. Ideal for smaller organizations or those heavily dependent on virtual machines, this strategy is quick but may overlook the flexibility benefits of cloud-native solutions and potentially become costly.

• Replatforming

Replatforming, or ‘move and improve,’ makes minimal changes for the transition to the cloud, leaving the core application architecture intact. This strategy is suitable for organizations planning to scale up their solutions, like an SQL Server database, in the cloud. However, like rehosting, it may not fully exploit the cloud’s potential.

• Repurchasing

In instances where legacy systems become too costly or difficult to maintain, repurchasing comes into play. This involves shifting to a cloud-based solution, like Salesforce’s CRM. While this approach proves cost-effective for managing outdated systems, it requires training both employees and end-users to ensure a smooth adaptation to the new system.

• Refactoring

Refactoring involves rebuilding the entire existing infrastructure from scratch to leverage all the benefits of the cloud, like serverless computing and auto-scaling. Despite being costly and time-consuming, this strategy can be highly beneficial in the long run.

• Retiring

Certain components of an infrastructure may become redundant or pose a security risk. In such cases, retiring these components before moving to the cloud can save costs and increase security.

• Retaining

If certain modules of your existing infrastructure aren’t compatible with cloud platforms or cannot be moved due to compliance issues, retaining them on-premise might be necessary. While rarely applied to an entire infrastructure, this strategy is often used in conjunction with others to create a hybrid cloud computing environment.
