On April 23, 2025, OS Management reaches end of life (EOL). Effective now, the service is no longer available to you in regions where you are not already using OS Management, or to new users with new tenancies. Before the EOL date, we recommend that you migrate your managed instances to the OS Management Hub service. If you are an Oracle Autonomous Linux user, see Important Maintenance Event. For more information, see the Service Change Announcement.
Migrating OS Management Instances to OS Management Hub
Migrate OS Management instances to OS Management Hub by discovering the OS Management resources in use, creating the equivalent resources in OS Management Hub, and migrating instances.
OS Management Hub provides a migration assistant to help you successfully perform each stage of the migration. The migration assistant supports bulk discover, create, and migrate operations to streamline moving to OS Management Hub. Migration can also be done manually using the OCI Console on a per-instance basis.
Note
Effective April 23, 2025, the Oracle OS Management service reaches end of life (EOL). OS Management is replaced by OS Management Hub, which provides an improved user experience with new features, including patch deployments through lifecycle stages, enhanced job scheduling, and reporting capabilities.
Before the EOL date, we recommend that you migrate managed instances from OS Management to OS Management Hub.
Stages of Migration
Migrating from OS Management to OS Management Hub is a three stage process.
Discover: Examine your OS Management instances and determine the software sources, managed instance groups, and scheduled jobs you require for your managed instances and resolve incompatibility issues.
Create: Create the required resources in OS Management Hub using the information that you determined in discovery. Add vendor software sources and create custom software sources, create groups, and create registration profiles.
Migrate: Unregister your instances from OS Management and use a profile to register them with OS Management Hub.
Before You Begin 🔗
Before migrating OS Management instances to OS Management Hub, you must do the following:
Verify that your OS Management instances are using Oracle Cloud Agent version 1.40 or later before you migrate. OS Management Hub requires minimum Oracle Cloud Agent version 1.40.
Create a new OCI instance and register it with OS Management Hub to familiarize yourself with the service by performing these tasks:
The migration assistant has additional policy requirements. To use the migration assistant, you need the following policy.
allow group group-name to inspect compartments in tenancy
allow group group-name to use tag-namespaces in tenancy
allow group group-name to use instances in tenancy
allow group group-name to inspect work-requests in tenancy
The first line allows the user group to list the compartments in the tenancy.
The second line allows the user group to update tag namespaces for resources in the tenancy. The migration assistant uses tags to track what resources have been migrated to OS Management Hub.
The third line allows the user group to list instances and update their tags to track migration status.
The fourth line allows the user group to monitor the status of the OS Management and OS Management Hub Oracle Cloud Agent plugins. The migration assistant uses this information to confirm that instance migrations are successful.
Migration Workflow 🔗
Use the following workflows for migrating OS Management instances to OS Management Hub depending on your use case:
Migrate instances to OS Management Hub using the appropriate profile.
Migration Assistant 🔗
The migration assistant provides a set of utilities to assist you with each stage of migrating instances from OS Management to OS Management Hub. To install the migration assistant, see Installing the Migration Assistant.
