Success! I followed your clear instructions and now I am running 2.7 and have 2.6 backed up!
Thanks for your patience and willingness to help. Possibly my last question for this thread:
The step by step instructions I linked earlier do not say anything about setting up the "cron" job. But as far as I can tell, I should be doing this. Is the following the appropriate place for me to start? I'm not expecting you to walk me thru it, just trying to find the best place to start. There's lots of information out there!
