Need to Clone 2TB HDD to 1TB SSD Disk

"My 2TB hard drive is about to failing and I’ve purchased a 1TB SSD to replace it. Plan to clone only used portion of the 2TB HDD (about 470GB) to the SSD. I have tried shrunk the 1.8TB volume size in Disk Management but failed. I’ve tried one cloning software but it does not support copy to smaller disk. Is there any professional tool that could clone only used space of the 2TB drive effectively? Thanks."
