-  * Create new Proxmox machine with similar parameters to old one 
-    * [[https://pve.proxmox.com/wiki/Windows_10_guest_best_practices|Windows 10 guest best practices]] 
-    * Remove created Hard Disc (scsi0) 
-  * Import disc images (repeat for all VDI discs) 
-    * As RAW images with all benefits (compression, thin provisioning, snapshots) of ''local-zfs'' storage: <code bash>qm importdisk 701 WIN7_C.vdi local-zfs</code> 
-      * 21743 MB VDI compacted file occupied 15,2G on ZFS with compression ratio 1.24x 
-    * As QCOW2 files on every file storage: <code bash>qm importdisk 701 WIN7_C.vdi local -format qcow2</code>

-  * Switch SCSI to IDE: <code bash>sed -i 's/scsi/ide/g' /etc/pve/qemu-server/701.conf</code> 
-    * Manually correct numbering conflict with CD-ROM ide drive 
-    * Setup correct boot order 
-  * Add one dummy (small size) hard disc to SCSI controller 
-  * Enable QEMU Guest Agent 
-  * Boot Windows, go to ''Device Manager'' and install missing drivers:

-==== NOT WORKING: Importing OVA file ==== 
-  * **Very slow method**, exporting OVA needs to copy all discs into exported and well compressed file. 
-  * In VirtualBox choose "**File**" --> **"Export Appliance"** 
-    * select to export all network cards and MAC addresses 
-  * Proxmox cannot import OVA files directly. Please unpack it with command <code bash>tar -xvf WIN7.ova</code> 
-    * After unpacking, manifest file .ovf will be available. 
-  * <code bash>qm importovf 701 ./WIN7.ovf local-zfs --dryrun --format qcow2</code> 
-    * WARNING: <code>warning: unable to parse the VM name in this OVF manifest, generating a default value</code> 
-    * Create account/Login to VMWare page and download [[https://my.vmware.com/group/vmware/get-download?downloadGroup=OVFTOOL440|ovftool]]
