After the preparation work is completed, you can use AOMEI Backupper to clone M.2 SSD to larger M.2 SSD, please follow the graphic tutorial for details.

Step 1. Launch AOMEI Backupper, click Clone in the left panel and select Disk Clone on the right menu.

Step 2. Select the original M.2 SSD containing Windows as the source disk and click Next.

Step 3. Select the larger M.2 SATA SSD as the destination path to clone the source disk and click on Next.

Step 4. Then you will see the Operation Summary page. Check SSD Alignment option to improve the writing & reading speed of SSD disk. Confirm all other settings and click Start Clone.

Tips:
💜 Sector by Sector Clone: it allows you to clone all sectors of a hard drive to another one including the bad sectors or empty sectors. And it will make Edit Partition becomes unavailable.
💜 Edit Partitions: you can adjust partition size of destination disk with this feature to fix the problem the cloned hard drive show wrong size issue. Also, you can use it convert disk type if the destination disk is different from source disk.

❆ The Edit Partitions feature is more practical and you have 4 options. Please select one or more of them if the new M.2 SSD is larger. 

>> Copy without resizing partitions: It will not resize the partition size.
>> Add unused space to all partitions: It will reallocate the unallocated space to each partition of the target disk, appropriate for the disk size.
>> Manually adjust partition size: It allows you to extend unallocated space to any partition on the destination disk you want. 
>> Convert the destination disk from MBR to GPT: It helps to convert the partition style of the destination disk if it is different from the source disk. 

#3. Safe Boot from Cloned M.2 SSD

1. To boot from a cloned M.2 SSD: If your computer has only one SSD slot, you should replace the old M.2 SSD with a cloned M.2 SSD; if there are two slots, just insert the cloned M.2 SSD into the empty slot.

2. Restart PC and press F2/F8/F11 or Del to enter BIOS, and change the boot order to boot from the cloned SSD.

3. Press F10 or save the changes, then restart the computer.

Most Concerned Questions on M.2 SSD Upgrading

1. Is there a risk of data loss during the M.2 SSD upgrade?

Properly upgrading an M.2 solid state drive will not result in data loss. However, human error or device error may cause data loss. It is strongly recommended to back up important data beforehand. Regular backups and careful handling can reduce this risk.

2. Will all my files and applications be transferred accurately?

The purpose of disk cloning is to copy everything, including files, applications and the operating system, but occasionally there are problems. For example, cloning progress stops when the target disk is not large enough to store all the data or when there are conflicts.

3. Can I clone my larger capacity M.2 SSD to a smaller one?

Yes, it is possible to clone larger drive to smaller drive using specialized cloning software, as long as the target device can accommodate the data used. Data reduction also helps in cloning to a smaller hard disk.

4. Does the M.2 SSD's speed affect the cloning process?

In general, faster SSDs facilitate quicker cloning, but the process mainly depends on data volume. For instance, with modern SSDs and efficient cloning software, the process could take around 30 minutes to 1 hour or even less for a 500GB used space cloning. Slower SSDs might extend to 1 to 2 hours or more.

5. Will my Windows license and activation remain intact after the upgrade?

Yes, Windows activation typically remains unaffected, but it's advisable to keep your product key handy just in case.
