    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,
    Dan
