I hadn't heard of clonezilla until just now.

The problem with that is your disk device will be under a different name, and this confuses the illumos boot system a bit.

I have no idea why that would be the case, but regardless...

... I can't say for sure.

That article is a bit old.

I've some questions that will help me give better advice.  There are no wrong answers here, just be as accurate as you can:

- Which revision of OmniOS are you running?
- Is your new SSD the same or greater size than the HD you have now?
- Do you have a CD/DVD or USB installer media?

Thanks,
