You must ensure that your migration plans do not mix VDDK mappings with copy-offload mappings. Because the migration controller copies disks either through CDI volumes (VDDK) or through Volume Populators (copy-offload), all storage pairs in the plan must either include copy-offload details (a `Secret` + product) or none of them must. Otherwise, the plan fails.

Storage copy offload is available as a Technology Preview feature for {project-first} 2.10.0 for cold migration and as a Developer Preview feature for warm migration.
For {project-first} 2.11, storage copy offload is available as GA for cold migration and as a Technology Preview feature for warm migration.

Storage copy offload is a feature that allows you to migrate {vmw} virtual machines (VMs) that are in a storage array network (SAN) more efficiently. This feature makes use of the command `vmkfstools` on the ESXi host, which invokes the `XCOPY` command on the storage array using an Internet Small Computer Systems Interface (iSCSI) or Fibre Channel (FC) connection. Storage copy offload lets you copy data inside a SAN more efficiently than copying the data over a network. Storage copy offload is available as a Technology Preview feature for {project-first} 2.10 for cold migration and as a Developer Preview feature for warm migration.
