With SuperDuper Boot Clone is anything irrevesible in High Sierra If Need To Go Back to Sierra?

Mac Pro - MacRumors Forums - forums.macrumors.com
Hi Guys,

For Boot drive I'm using a 480GB PCIe SSD (OWC Mercury Accelsior E2)

My boot clone is a 1TB WD Black, partitioned into three individual boot-able drives. I use these three sections as rolling boot back-ups, cloning via SuperDuper every 3-4 days.

This way, I can revert back to 3 days ago, 7 days ago, 10 days ago etc... If I ever discover something going sideways with my system. It's an insurance plan for drive failure, and insurance plan for an update causing instability.

Question: Given this back up plan, If I install High Sierra, is there anything irreversible here? Normally don't sweat testing out system updates, but the new APFS thing has me thinking out loud on this.

System:

2012 MP 5.1 12Core 3.46

GPU : Stock ATI 5770

Boot : OWC PCIe SSD

Bay 1 : 1TB HDD (3 Partitions for Boot Back Up)

Bays 2-4 : 3x 6TB HGST HDD's in RAID5 using SoftRAID

External : 3x 8TB HGST He8's in OWC Qx2 for 3 Time Machine Back Ups

No Bootcamp, No Windows

No nVidia Cards, but planning purchase of 1080 or 1080ti

Thanks!
