I worded my first paragraph clumsily.  I have an internal 1TB SSD with two 500G partitions.  One has El Capitan, and the other has Sierra.  It’s the Sierra partition I’d like to (am forced to) update to High Sierra, as it's required for the latest version of FCPX.  Apple strikes again.

I have a MacPro5,1 - the last cheese grater model, and I’d like to install High Sierra on a partition that also has El Capitan on it so that I can convert FCPX projects to XML so I can finish projects started in FCPX in Pr and Ae, and work on them on El Capitan, which is working great.

When I started to install High Sierra on my Sierra partition, the installer told me I need to update the firmware.  I bailed.

My question is: 

If I update the firmware, will it bork my MacPro5,1 so that it will no longer boot from El Capitan?

I’ve searched for an answer, and most people seem to throw fate to the wind and commit to High Sierra forever.  I’m not that guy.

Can anybody help, or direct me to some info?  

Thanks,
Jim C.
