Oh wow. Yes, I was trying to install SP Upgrade on the old site.
I totally missed that step in the tutorial - to install J2.5 in its own directory.
In fact, I don't see it there now but I might be totally blind. Thank you Ed! I'll try that now.
OKAY, it worked. I like SP Upgrade!
Once the upgrade was done, I had to:
1) convert my homemade template to 2.5. I tried the OSTraining tutorial, but it was more appropriate for more complicated templates. This one is totally pared down. So I followed the advice in a Lynda.com tutorial and it worked like a charm.
2) find a new drop-down menu. After one time-consuming false start, I found
swMenuFree, which is great.
3) buy an upgrade to the calendar component, Art Calendar.
Now I need to install the remaining extensions which I have already and finish the current state of the site as prep to finish building the site.
My new site is in a subfolder on the server. I will contact Bluehost to confirm the steps I need to take to replace the old site with the new one. IF you have any tips on that, I'm listening.
Thanks again for everything you do.
