A volume cannot span across enclosures, i.e, to do a 16 drive RAID volume across 2 Thunderbay 8's, you need the Pro version.
Seriously, I have no idea why you keep saying that. I never said I had or wanted a volume spanned across enclosures. Are you a bot?
You were asking a question about how many enclosures per license, which is unlimited, and I was clarifying the one limitation. Plus there was another comment in this thread related. Another issue is this thread is off topic for its title, this discussion is more of features. Which is fine, but I have to take into account the title of the thread.
And the issue that there is no longer clear sub-threading, so a reader may not be clear who or what I am responding to. That subject is over!
Users who are under warranty receive a free upgrade to SoftRAID 6.
How would one go about getting this upgrade?

Enter your 5.x license here and it will give you your options.
We made the decision to discontinue SoftRAID lite. You are not stranded, you can convert to Apple's RAID and keep going without losing access to your data.
You can run either version, 5.8.4 or 6.0, and "convert" to Apple RAID, no problem.
Apple has made supporting macOS extremely difficult and engineering intensive, and an inexpensive software RAID is not practical right now. Sorry about this. We actively support our enclosures with software RAID, and added 4 and 5 support to existing customers, but supporting third party enclosures for standalone Lite is not viable.
How do I convert my softraid 1+0 drives to Apple RAID on my Mac Mini M1 without losing my data?
RAID 1+0 is difficult. I don't have a guaranteed way for you to do it, so you need to backup, and restore. The way Apple's RAID 1+0 works is very different than SoftRAID, so we cannot convert it.
