An NVMe drive fills up faster than expected: games, project files, and Windows updates all compete for the same small partition. Moving to a larger NVMe keeps the installation intact, provided the clone copies the boot files correctly.
This guide explains what to prepare, how to clone NVMe to NVMe with Qiling Disk Master, and how to make the new drive boot and use its full capacity.
Cloning copies the whole installation, including the EFI system partition and recovery files, so nothing has to be configured again.
If the PC has only one M.2 slot, use an enclosure or adapter as described in How to Clone an M.2 SSD with Only One Slot.

A few minutes of preparation prevents the most common clone failures.

Qiling Disk Master clones a drive sector by sector or intelligently, copying only the blocks in use. Download and install it first.
Step 1. Open Qiling Disk Master, choose Clone, and then select Disk Clone.

Step 2. Select the current NVMe as the source disk and click Next.

Step 3. Select the new NVMe as the destination and confirm the warning about the data on it.

Step 4. Preview the disk layout, adjust the partition size to use the extra capacity, and tick Optimize for SSD.

Step 5. Click Proceed, wait for the clone to finish, then shut down, swap the drives, and keep the old NVMe until the new one boots.

If the new drive is meant for a different machine, follow the migration steps in Migrate Windows 10 to NVMe or M.2.
No. Any NVMe drive that fits the slot and has enough capacity will work, regardless of the manufacturer.
Only when the data in use fits. Most tools resize partitions during the clone, but the margin is small.
Yes. The motherboard is unchanged, so the digital license still applies after the swap.
It depends on the amount of used data. NVMe drives are fast, so a typical system clone finishes in minutes.
Reseat it, check the slot shares with SATA ports, and look for the drive in the BIOS before cloning.
Before changing drives or partitions, create a full Windows backup. Qiling Disk Master creates a system image you can restore from.
Step 1. Open Qiling Disk Master and select System Backup to include Windows and the boot partitions.

Step 2. Save the image to a drive other than the system NVMe and start the backup.

Step 3. Click Proceed to start the system backup and wait patiently until it finishes. You can also tick Shut down the computer when the operation is completed to power off automatically.

Step 4. If the clone or the swap goes wrong, restore the image to return Windows to its working state.

A larger NVMe is the simplest upgrade for a machine that is running out of room. Connect the new drive, initialize it as GPT, and clone the system NVMe with Qiling Disk Master while SSD alignment is enabled. Then set the new drive first in UEFI, boot once to confirm Windows starts, and extend the partition into the extra space. Keep the old drive untouched until the new one has proven itself, and take a system image beforehand so a failed clone never becomes a lost installation.
