Clone root partition

Hello!
These days i have been thinking on cloning my root partition (at the end of the partition table /dev/sda7) to my first one (/dev/sda1). The first try i would perform was something like this:
- clone the root partition with a live cd (https://wiki.archlinux.org/index.php/Disk_cloning)
- adjust /etc/fstab on the new one
- reinstall grub

Is this right? What I actually want is extra space on my home partition (sda8), which is the last one. I could re-size them, but this operation has to be done on 3 partitions, including the root one, and it is a little bit dangerous.  The other question is if this is worth it, from the performance point of view (faster disk access) to the practical (not having to move data trough resizing).
Thanks

Re: Clone root partition

Cloning partitions with different sizes using dd could be dangerours.
I would suggest you using rsync instead.
No need to boot from live cd too.

Re: Clone root partition

Thanks losko!
Worked almost like a charm. Had some issues with grub-mkconfig detecting the new UUID, the chroot method described by the wiki page didnt work. But then i edited grub.cfg by hand. Later, just reinstalled grub and ran again mkinitio and grub-mkconfig from the new partition.
