Upgrading to High Sierra on existing Raid 0

I am using a software Raid 0 with two 512 GB SSDs in my Mac Mini. Everything(data and system files) is on that Raid 0.


I read that High Sierra will automatically convert any SSD to APFS. I also read that software Raid 0's can't be used to install High Sierra on them.


So what will happen if i try to upgrade to High Sierra? Will my system become unusable? Will i lose all the data on my SSDs?
