Migration advice for my Thunderbay 4 (12TB) w/ HFS+ Raid5

Hello!

I have a Mac Pro (aka flower pot) and bought a Thunderbay 4 12TB with softraid in 2015. It has been setup as RAID5 w/ an HFS+ filesystem ever since. Since I replaced 2 drives in the last two years based on predictive failure advice.. hoping to keep this unit running and useful..

I have stepped up to the beta 6.0.* softraid after stepping up this intel mac to Big Sur, but even the latest beta does not let me mount my raid5 hfs+ filesystem. (If I connect my thunderbay to my macbook pro retina 2012 laptop the filesystem works great on Catalina).. 

Here are my questions.

1) Is it possible to mount my HFS+ volume on my Big Sur (Intel mac) - even if just readonly - or do I have to wait until a future release?

2) Once SoftRAID for Big Sur officially comes out.. will my HFS+ still be the recommended filesystem to use? I have a big USB drive backup of my volume, so I can reformat if necessary to migrate.

The latest SoftRAID release, 5.8.4, is not compatible with Big Sur. We will be doing public beta's until 6.0 is ready, which could take a couple months. New betas will be released as we go, and you will be auto notified through the SoftRAID Monitor.

here is the link to the beta: SoftRAID 6

Read the release notes!

Make sure you "Approve" OWC as an Identified Developer in Security Preferences in MacOS when prompted.

Let us know if this does not work.
