Is it possible to clone all data from one hard disk to another ?

[andy8]

Hi,

I currently have installed one Seagate IronWolf Pro 16TB harddisk.
I want to transfer all the data to another newer Seagate IronWolf Pro 20TB harddisk.

Is it possible to do this using my Asustor NAS itself ? Could I use the ADM software to transfer all data to the new Harddisk, via existing harddisk ?
I would like to remove my 16TB hard disk (to sell) and only use the newly installed 20TB disk.

Or do I need to use some cloning software and my laptop perhaps to transfer data to new hard disk?

Please help if someone has any suggestions on this, it would help me greatly. Thanks

The best method is to clone but officially you can't do this on the NAS unless you really know what you're doing i.e. using dd to clone, then resize the partition, finally expand the fs. The volumes also needs to be unmounted for consistency.

The safest method is to transfer between volumes using the built-in ADM File Explorer in the web portal then reinstall back all the apps.

Thank you Nazar for the reply. I have created a RAID 1 mirror with both the disks.
