Oh, I forgot to add that the 5.3 version wasn't working properly. My server people did something weird to imagemagick (I've spent the last three days trying to figure out what). GD2 works though. So, I probably need to change:
$mogrify_command = "/usr/bin/mogrify";
to whatever the GD2 is?
But if I change it, will the upgrade work?
Is there anyway to go ahead with a fresh install, yet use my old database?
Thanks for our help. I know this is all kind of a mess. I'm doing the best I can with it.
