Just a short post to report that I finally took a deep breath and went through the motions to clone my 500 GB SSD drive to a new 1 TB SSD. I used Clonezilla and it went rather well.
Afterwards, I found it duplicated the partition size to the new drive, so there was roughly 500GB unallocated. A quick Google search revealed how to extend the partition, which I did in about 15 seconds. Summary – I have a 1TB usable system SSD!
The next step will be to perform the Windows 10 upgrade on it. Yeah, I know – better late than never, right? Hopefully I’ll have it done by next week – I’m tentatively targeting Saturday as upgrade day.
