System on SD card, how to move it to HDD

[turgut kalfaoglu]

Hi. I have my orange PI OPT 3 LTS  running Ubuntu..

The system is installed in /dev/mmcblk0 (I believe that's the SD card?), and I just checked with gparted that it still has the Android it came with on /dev/mmcblk2 (I believe that's the internal memory?)

 

Anyway, I would like to move Ubuntu to the external USB HDD I added.  I created a /dev/sdb2 for it in ext4.

I launched nand-sata-install a few times, but I'm afraid of picking the wrong options.. Which options should I pick to ensure that it does not destroy my Ubuntu installation in the process?

 

Many thanks,

A backup is the correct option

I thought of the same thing this morning Since its OS is on an SD card right now, I can just power it off, take it out and do a tar compress of the whole thing on my laptop

Many thanks!

As a followup, I easily migrated the OS to the HDD.. Here is what I did:

 

• First I used gparted to shrink the current HDD partition and created a 50GB partition (just shrink the current partition by 50GB, wait 6 hours (it took that long!) and create a partition in the new blank space.
• I had some mounted partitions to the root folder, like /media  and /media2  .. I removed them from fstab, because I couldn't unmount them (gave errors), I just rebooted the machine.
• I launched the nand_sata_install and followed the prompts..
• Waited about 15 minutes, it was done, rebooted. Done!
