ISO migration, also known as image migration, works as follows: Burn the ISO file of the current HCI version to a USB drive, then insert the USB drive into the server to be migrated and set the server to boot from the USB drive. Alternatively, if migrated from a VM platform, upload the ISO file to the virtualization platform, shut down the target VM, and reconfigure it to boot from the ISO file. Once booted, the ISO system will share all disks on the server to be migrated. After that, the hyper-converged platform directly converts all data on these disks into virtual qcow2-format disk files compatible with the hyper-converged platform. Finally, a new virtual machine is created using these qcow2 disk files.
