I have noticed that I have less and less space on my 1TB hard drive. I have been eliminating stuff to make more room and the amount of available space isn't really changing that much. Today I discovered that System Data is using 804.25 GB of my space when I check "About This Mac" under storage.
I also noticed when I look in "About This Mac" under Overview - System Report that I have 2 entries for my Mac. These have different Mount Points. I had attached a print screen of this.

1 - Does updating to a newer version keep all the old system data on the computer?
2 - How can I free up this space?
I wondered if I should run Disk Utility or what else I could do?
Thanks for your help

Is there some associated issue?

in this context it is your user data.
You get a better picture from the Terminal.app copy & paste:
diskutil list internal

Try something like OmniDiskSweeper for a GUI to get a good look at itemized file size and location:
