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