You can migrate a MongoDB deployment from one Ops Manager project to another project.
Historic metrics for the MongoDB deployment don't migrate to the new project.
If you have backup enabled and want to retain snapshots:
If you want backup enabled for your MongoDB deployment in the new project, prepare your backup components.
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.
(Optional) If the new project is a new Ops Manager, update the mmsbaseurl setting.
The MongoDB deployment servers should appear on the Servers and Agents tabs.
Activate the backup and monitoring MongoDB Agent functions in the new project.
(Optional) Start backups.
This step permanetly deletes your old project and its related artifacts.
Terminate all backups in the old project.
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.
Completely remove the MongoDB deployment from the old project.
