Is this the OS drive?
How much space is consumed ont he current source drive?
The actual user facing difference between PCIe 3.0 and 4.0 is far less than the uber benchmarks imply.
If you do choose to migrate to the new drive, you can do it via an Image, rather than a strait 'clone' thing.
Basically, you write an Image off to the HDD, Boot from a Macrium RescueUSB, and recover that Image to the new drive.
Specific steps:
--------------------------------------
Assuming you have another drive with sufficient free space to hold the entirety of your current m.2 drive:
- Download and install Macrium Reflect
- Run that, and create a Rescue CD or USB (you'll use this later). "Other Tasks"
- In the Macrium client, create an Image to some other drive. External USB HDD, maybe. Select all partitions. This results in a file of xxxx.mrimage
- When done, power OFF.
- Swap the 2 drives
- Boot up from the Rescue USB you created earlier.
- Recover, and tell it where the Image is that you created in step 3, and which drive to apply it to...the new m.2
- Go, and wait until it finishes.
- That's all...this should work.
