Replace 1 TB m.2 SSD with 2 TB m.2 SSD (lemmy.ml)

Not specifically Archlinux, but I am using Archlinux on my laptop, so I thought I'll ask here.

I am planing to replace my 1 TB M.2 SSD in my laptop with a 2 TB M.2 SSD, and I am wondering how to clone the whole 1 TB SSD and restore it onto the 2 TB M.2 SSD.

I have read about people using $dd for that, but I never did that. Can anybody confirm that this is possible?

I am running two partitions, one boot and the other one is a crypt device with btrfs + subvolumes inside.

Is there anything I have to consider, before doing this?

Thank you for your time.

The Arch wiki has some really good info on using dd for cloning. I've done it myself successfully with dd, but double and triple check to make sure your command is correct before continuing. Both drives would need to be connected to the same machine at the same time (new drive in a USB enclosure or in a spare PCIe slot)

It might be worthwhile to check out GUI alternatives to dd if you feel more comfortable in a GUI vs terminal:
