After the completion of an HCX Bulk Migration, a large number is appended to the VM folder name at the destination site. For example, the folder name might appear as VMname_1738220452
.
VMware HCX
The number added to the VM folder name is a Unix timestamp that indicates when the migration was performed. This behaviour is by design. Bulk Migration doesn't remove the original VM at the source site, allowing for quick recovery after a switchover if needed. There is no impact on the VM's operation.
