Q: Will Upgrading Wipe my Hard Drive?

Having a boot clone in your arsenal will allow you to fall back if necessary.
To answer your question, no typically you lose no files upgrading OS X. Some Application may not longer run, and files un-accessible in that way. So do your due diligence before you proceed.

If you don't have at least 8GB of RAM you may be dissapointed.

My whole business is on my computer and if it gets deleted my business is in serious trouble! My 1tb external hard drive somehow is ineligible to be backed up on by Time Machine. I'm not willing to buy a whole new hard drive just to upgrade my computer.
A large external backup drive can be purchased for less than $100. How much is your business worth?
Why do you believe your current 1TB HDD is 'ineligible' to back up your MBP?
