Compose to IBM Cloud Databases: The Migration Guide

A compilation of tutorials on how to migrate Compose databases over to IBM Cloud Databases.

Since the release of IBM Cloud Databases three years ago, we have received tremendous interest from Compose customers looking to upgrade their resources to the IBM Cloud Databases family. In this article, we enumerate the benefits of IBM Cloud Databases and compile guidance on how to migrate to your new IBM Cloud Databases instance.

One important difference to keep in mind is that IBM Cloud Databases is really the culmination of what we’ve learned on Compose by running tens of thousands of databases for customers around the globe, 24×7, 365 days a year for the last decade.

Additionally, in keeping with the strengths of Compose, IBM Cloud Databases has added features and capabilities that distinguish it from Compose and other cloud services running open-source databases:

Horizontal integration with other IBM Cloud services to provide a cohesive experience for customers that includes access control, encryption management, technical support and billing.
Vertical integration with IBM Cloud infrastructure to allow us to offer the service at a much more economical price and provide more fine-grained control over scale up and out.

Other key features of IBM Cloud Databases
