Migrate vm to smaller vm

[sg29]

Hello,

I'm actually trying to save an old physical machine (win 10 x86) to a virtual machine.

I managed to clone it from physical to virtual with no real problems and it actually works fine on vm (the physical on died, rip).

But i am hitting a wall on the last step, reducing virtual disk size (i need it reduced because i do not have much space on the replication server).

The physical machine has a 250Go disk but with only 59Go used for the system partition, rest is unused.

I have tried multiple solutions and all failed...
clonezilla disk to disk with -idcs on local disk
clonezilla disk to disk with -idcs on distant vm
clonezilla partition to partition on local
clonezilla partition to partition on distant
aoemi backuper to local partition

So is there a proper way to do that ?

Best regards,

Seb

hi,

you can use diskpart tool (preinstalled on windows i think) to shrink the volume to the desired size, and then use sdelete (in microsoft sysinternals) to clear up the free space on the logical disk.

afterwards you can use qemu-img convert to create a new disk this time it will be smaller

Could you please tell how to move a physical Win to virtuell? i have still a win7 - running fine so far but still would be nice to move it.
