I moved from 256 to 1tb.

First I used an usb-c adapter for the new ssd, this allowed me to copy all the files over from the existing disk using desktop mode and some terminal commands. Even the hidden files etc. After proper formatting and prepping the new disk.

Then I just replaced the old with the 1tb. Everything was the same: no loss of anything. The full 1tb was usable as well.

I followed a tut online just for the commands. If you don’t find it: shoot! I will digg in my history :)
