This post is the first video of a multi-part video series on “Zero Downtime Migration” which is part of our training DBA to Cloud DBA.
In this blog post, we’ve covered the Zero Downtime migration overview and capabilities to migrate the database on the cloud.
In this video, I will discuss the overview and capabilities of the ZDM.
What Is ZDM?
Zero Downtime Migration (ZDM) is an oracle software that is used to migrating your On-Prem or OCI-classic database to Oracle Cloud Database (VM DB, ExaCS, Bare Metal) and on to the Exadata Cloud at Customer) with the minimal downtime on production workloads.

Overview: Zero Downtime Migration Software Key Points
- Oracle Zero Downtime Migration (ZDM) is Oracle Maximum Availability Architecture (MAA) recommended software to migrate Oracle Databases to the Oracle Cloud.
- It helps to keep the migration process as simple as possible and aims to have minimal downtime on production workloads.
- The source databases can be On-Premises or on Oracle Public Cloud Gen1 (OCI-C).
Note: To know the difference between OCI & OCI-C check here
- The target databases can be deployed as Database Cloud Service on Oracle Cloud Infrastructure (OCI) Bare Metal, Virtual Machine, Exadata Cloud Service, or Exadata Cloud at Customer.

- It automates the complete process of migration & reduces human errors.
Supported Configurations For ZDM
1) Supported Platforms for the Zero Downtime Migration Service Source Host
- Oracle Linux 7 or later releases.
2) Supported Database Versions for Migration:
- 11.2.0.4
- 12.1.0.2
- 12.2.0.1
- 18c
- 19c
Note: the source & target Database version should be the same database version.
3) Supported Database Architectures for Migration
