Migrate a MongoDB Deployment to a New Project

You can migrate a MongoDB deployment from one Ops Manager project to another project.

Considerations

Historic metrics for the MongoDB deployment don’t migrate to the new project.

Procedure

1

Optional: Download snapshots.

If you have backup enabled and want to retain snapshots:

1. Download any snapshots that you want to keep:

   • Download the snapshots for a replica set.
   • Download the snapshots for a sharded cluster.

2. Stop all backups.

   Important

   All existing snapshots remain available for download until they expire, but Ops Manager captures no new snapshots.

2

Optional: Prepare backup components.

If you want backup enabled for your MongoDB deployment in the new project, prepare your backup components.

3

Prepare the old project.

1. Deactivate the backup and monitoring MongoDB Agent functions in the old project.
2. Unmanage the MongoDB deployment in the old project, but continue to monitor it.

4

Prepare the new project.

1. Create a new project to use as the destination project.
2. Click Settings in the left navigation.
3. Note the Project ID value on the Project Settings tab.
4. Create a new Agent API key.

5

Prepare the MongoDB Agent.

Note

If you have multiple deployments in your project and a MongoDB Agent installed only on the hosts that you plan to move, you must install new agents on servers that you will not move to the new project.

1. Stop the MongoDB Agent.

2. Edit the MongoDB Agent configuration file to update the mmsGroupId and mmsApiKey settings with the values from for the new project.

3. (Optional) If the new project is a new Ops Manager, update the mmsBaseUrl setting.

4. Start the MongoDB Agent.

   The MongoDB deployment servers should appear on the Servers and Agents tabs.

6

Migrate the MongoDB deployment.

1. Activate the backup and monitoring MongoDB Agent functions in the new project.
2. Add the MongoDB deployment to your new project.
3. (Optional) Start backups.

7

Optional: Remove the old project.

Warning

This step permanetly deletes your old project and its related artifacts.

1. Terminate all backups in the old project.

   Important

   If you don’t terminate all backups in the old project, all existing snapshots remain available for download until they expire and occupy disk space. You can’t remove the MongoDB deployment and delete the old project unless your terminate all backups.

2. Completely remove the MongoDB deployment from the old project.

3. Delete the old project.
