Disk migration - Move to a new disk

• Use clonezilla to clone the drive
• In the new booted linux system, use gparted to extend the encrypted partition
• After that you need to resize the lvm volume which is part of the encrypted partition, to do so:

sudo lvdisplay # This is to get the mountpoint, although it usually is /dev/vg/root
sudo lvextend –l +100%FREE [MOUNTPOINT]
sudo resize2fs [MOUNTPOINT]

The new disk will have the new size of the disk
