Migrate Debian 10 Installation to a New 500GB SSD

This article will guide you through the process of migrating your existing Debian 10 installation from a 120GB SSD to a new 500GB SSD. We will cover key concepts, such as partitioning, cloning, and system configuration. By the end of this article, you will have a smoothly running Debian system on your new SSD.

Why Migrate to a New SSD?

A new SSD offers more storage capacity, faster read/write speeds, and greater longevity compared to older SSDs. Migrating your Debian installation is an excellent way to take advantage of these benefits.

Partitioning the New SSD

Before migrating your system, you will need to partition the new 500GB SSD. In this section, we will walk through the process of creating three partitions:

A 512MB EFI system partition
A 4GB swap partition
A root partition, consuming the remaining space.

Begin by connecting the new SSD to your computer, then follow these steps to partition the drive:


 sudo fdisk /dev/nvme0n1

Create a new EFI System partition:


 g
 n
 < 512M
 ef00
 a
 1

Create a new swap partition:

Create a new root partition:


 n
 < remaining space
 8300
 a
 3

Write the partition table:

After partitioning the drive, format each partition using the appropriate file system:


 sudo mkfs.fat -F32 /dev/nvme0n1p1
 sudo mkswap /dev/nvme0n1p2
 sudo mkfs.ext4 /dev/nvme0n1p3

Cloning the Debian Installation

Now that the new SSD is partitioned, you can clone your existing Debian installation to the new drive:


 sudo dd if=/dev/nvme0n1p3 of=/dev/nvme0n1p3 bs=4M status=progress oflag=sync

Updating the EFI System Partition

After cloning, update the EFI system partition to ensure your new SSD boots correctly:


 sudo mount /dev/nvme0n1p1 /mnt
 sudo mount /dev/nvme0n1p3 /mnt/boot
 sudo cp -r /boot/efi/* /mnt/

Configuring GRUB and System Settings

Configure GRUB and system settings to finalize the migration:


 sudo mount --bind /dev /mnt/dev
 sudo mount --bind /proc /mnt/proc
 sudo mount --bind /sys /mnt/sys
 sudo chroot /mnt
 grub-install /dev/nvme0n1
 update-grub

Partition the new SSD
Clone the Debian installation
Update the EFI system partition
Configure GRUB and system settings
