Obviously having a backup is crucial no matter what you do.  However,  
I can say that I have had good luck upgrading two separate instances  
of Xsan that originally date back to version 1.0/1.2.  The upgrades  
happened as new patches and 2.0 became available, and have gone  
smoothly.

As a datapoint, I have/had volumes that are filled with 25TB worth of  
small to mid-size files (text/html files to hi-res tiffs) that took  
what was probably near 24 hours to upgrade the filesystem.


Good luck,
