vCenter Migration Utility


If a Virtual Machine's MoRef is changed due to migration to new vCenter / inventory change in vCenter, you would receive the error "Object "vmname" is not found". Please see KB1299 for more details.

This utility is designed to assist in re-mapping the MoRef ID's of the Virtual Machines you are backing up and/or replicating using Veeam Backup & Replication, so that backup incremental chains remain intact, after an inventory change in VMware vSphere vCenter. Do not run any jobs before using the migration tool otherwise, the migration process won't be possible.

Please note that this utility is provided as a courtesy, and is not supported by Veeam Technical Support. Use it at your own risk.

This tool cannot fix jobs targeting a Cloud Connect repository. You must perform an Active Full backup.

Important! If you are migrating to a 6.5U2 VCSA, VMware has a new migration utility, which could preserve existing VM MoRef IDs:
This VMware utility only works for a 5.5 VC to a 6.5U2 VCSA!


Veeam Backup & Replication tracks Virtual Machines in its jobs by a Managed Object Reference ID (MoRef), which will change when moved to another vCenter, or removed and re-added to inventory.


Please download this bundle: tool and instructions.
Before using this tool, it is highly recommend to take a configuration backup of your VeeamBackup database.


  • The utility will work only with a source vCenter migration. If Replication target vCenter is changed, you will need to manually map source VMs to their replicas.
  • If for some reason you have already added the new vCenter or ran any jobs which will have added new Ref-IDs to the database, you can roll the Veeam Backup & Replication database back using the Configuration Restore function.


If you use the VMware provided VCSA Migration tool, you will need to remove and re-add VMs to jobs manually through the new VCSA after adding it to Veeam.

VMware highly recommends migrating to a VCSA, as they are phasing out the Windows based vCenter.
