Oracle Zero Downtime Migration (ZDM) – Hands-On Guide

Learn to migrate Oracle databases to OCI with minimal downtime using ZDM

Migrating Oracle databases to the cloud with minimal downtime is one of the most challenging tasks for DBAs. Traditional approaches using Oracle Data Guard or Oracle GoldenGate require deep expertise, complex configurations, and significant manual effort, making large-scale migration projects time-consuming and error-prone.

To address these challenges, Oracle introduced Zero Downtime Migration (ZDM)—a powerful tool designed to automate and simplify Oracle database migration projects.

This course teaches you how to use Oracle Zero Downtime Migration to migrate on-premises Oracle databases to Oracle Cloud Infrastructure (OCI), Exadata Cloud at Customer, and Exadata Cloud Service, with minimal downtime. ZDM leverages proven technologies such as Oracle Active Data Guard and Oracle GoldenGate, while hiding their complexity behind automated workflows.

ZDM supports a wide range of source database architectures, including single-instance and RAC, CDB and non-CDB, and both Standard and Enterprise Editions.

By the end of this course, you will be able to:

• Install and configure Oracle Zero Downtime Migration

• Understand ZDM workflows and migration phases

• Configure ZDM migration jobs

• Implement physical online migrations

• Implement logical online migrations

• Monitor, manage, and troubleshoot migration jobs

Each concept is followed by hands-on practical exercises, supported by video demonstrations and downloadable practice materials. You will build a practice environment that closely resembles real-world migration scenarios and apply ZDM end to end.

This course is designed for Oracle DBAs and migration engineers who want to implement cloud migration projects confidently and efficiently.

If you are planning Oracle database migrations and want to reduce downtime, risk, and manual effort, this course will give you the practical skills you need.
