To migrate a storage VM in vCenter, follow these steps:
1. Log in to the vCenter Server with your administrative credentials.
2. Open the vSphere client and navigate to the host that is running the storage VM.
3. Right-click on the storage VM that you want to migrate and select Migrate.
4. In the Migration wizard, select the destination host and datastore for the storage VM.
5. Choose a migration type based on your requirement, such as cold migration, hot migration, or storage vMotion.
6. On the next screen, review the migration settings and check the box to confirm that you have verified them.
7. Click Finish to start the migration process.
The migration process may take some time depending on the size of the storage VM and the type of migration selected. You can monitor the status of the migration from the vSphere client. Once the migration is complete, the storage VM will be running on the new host and datastore.
