Easiest way would be to clone the existing SSD onto the new one since the XPS 8950 has two NVME slots. You can use Macrium Reflect (free) to clone the old SSD onto new one. Make sure you follow the steps to change order and size of partitions on the new SSD so you'll be able to increase the size of the C: partition to use all available free space on the new SSD after all the other partitions have been cloned onto it (without increasing their sizes). So drag C: partition onto the new SSD last so you will be able to expand it to use all available free space.
What is the suggested way to upgrade my current C: from a 256GB 2230 to a 1TB 2280? Currently the 256GB has Windows 11 Home on it. I had just upgraded my ram from 8GB to 32GB using 2x16GB Crucial 4800MHz without a problem. Do I do a system image restore on the new 1TB SSD 2280? If so, what about the apps I currently have on the 256GB?
