After all VMs with snapshots were copied from the old system to a hard disk, the hard disk was plugged into the new ESXi host and successfully recognized. Afterwards the hard disk was mounted as datastore and the data of the VMs were accessible. The VM folders have been copied to a RAID in the new server. Next I added the VMs to the inventory.
Unfortunately I can't start the VMs after copying. I get the following error when starting:
Failed to power on virtual machine NAME_OF_MY_VM. Unable to enumerate all disks. Click here for more details.
If I let more information be output, I get this displayed this:
Power On VM
Key:
haTask-9-vim.VirtualMachine.powerOn-1219
Description:
Power On this virtual machine Virtual machine NAME_OF_MY_VM State Failed - Unable to enumerate all disks.
Errors:

The specified feature is not supported by this version
The old server runs esxi 5.0 and the new 6.7.
