Moving RHEL 6 to new HDD, EFI and LVM2 questions

Hello everyone,

one year ago I installed RHEL6 on one HDD. This was my first RHEL installation, so I did not spent so much time on partitioning and so on. The partition table looks like this:

sda1: /boot/efi; 200MB

sda2: /boot; 200MB

tmpfs: /dev/shm: 50GB

LVM2:

/dev/mapper/lv_root: 50GB

/dev/mapper/lv_home 50GB

Now I want to change the HDD.

I have done that some times using "dd" or "cp -ax" and fitting the partitions and so on.

- But how to deal with /boot/efi? can I just dd or cp it?

- And what about the LVM? dd the partitions themselfs or the whole LVM?

With best,

Mario
