Taylor,
I know this is quite an old post, and this is probably a shot in the dark; however, I seem to be struggling to find some relevant info on how to proceed with a project that I am working on. I don't know if you still check the Moodle forums or what.
Essentially, my organization would like to move to Moodle 2.0 from our currently existing mixed 1.8 - 1.9 farm. We have a very disorganized and poorly pieced together environment (from what I can tell), and was essentially looking for guidance on how to proceed. I was looking MySQL clustering, etc. to attempt to establish a MySQL HA solution for our Moodle farm; however, from what I have read this is not the way to go with Moodle.
My understanding is that SFSU is ran like a well-oiled machine, so if you could assist with some manner of guidance in any way shape or form it would be much appreciated.
Thank you,
P.S.
