“I’m intending to upgrade my hard disk drive with Windows 10 installed to solid state drive. As I’m unwilling to reinstall Windows 10 operating system, I decided to migrate it by cloning. The problem is that the capacity of the HDD is 1TB and the newly purchased SSD is 256GB. Is it possible to clone Windows 10 HDD to smaller SSD?”
Due to SSDs’ various merits like faster speed and high price, it is wiz to upgrade Windows HDD to smaller SSD. And you can avoid the trouble of reinstalling Windows 10 by cloning HDD to smaller SSD. In fact, it is a rather simple task to clone Windows 10 disk to smaller, if the used space on the target disk is not larger than the capacity of the destination SSD and you employ proper disk cloning software.
AOMEI Partition Assistant Professional is just the right one; it offers two ways to copy disk: "Sector-by-Sector Clone" and "Clone Disk Quickly". The latter one only copies used space on the source disk to destination one, allowing you to clone Windows 10 HDD to smaller SSD if the used space on the HDD is not larger than the capacity of SSD. What's more, if the destination disk is not large enough to hold all the data on the source HDD, it supports you to migrate only OS-related partitions (data partition not included) to smaller SSD as well via Migrate OS to SSD function.
AOMEI Partition Assistant Professional can not only work with Windows 10, but also with Windows 7/8/8.1, XP and Vista. If you need to clone Windows Server 2019/2016/2012 (R2)/2008 (R2) to SSD, you can employ AOMEI Partition Assistant Server.
To clone Windows 10 HDD to smaller SSD, connect the target SSD to your computer well at first; then, install and run AOMEI Partition Assistant Professional.

Step 2. Choose the Windows 10 HDD as the source disk and click “Next”.

After moving Windows 10 HDD to smaller SSD by cloning, if you want to keep old HDD and boot from SSD, you need to enter BIOS to change boot priority to SSD. If you clone GPT disk to smaller MBR SSD or MBR disk to GPT SSD, you also need to change boot mode between Legacy and UEFI.
