Simply connect the disks into the new machine and activate the LVM with the already mentioned:
sudo vgchange -ay

If the OS is actually onto the LVM you would need do few more steps but the principle is the same. If the LVM is only for data, no OS, then only moving the disks and doing the vgchange should be enough.
0 lvms available. Physical extent allocated is 0. It is messed up
