RE: Upgrading 1.4.2 to 2.1

Vitali,

Take it from me, you'll want to backup, rebuild and restore.  We did the 
upgrade last June and had problems with daily fsm panics after that.  Apple 
finally fixed our issues two weeks ago.  That's over a year with our Metadata 
controllers crashing daily. You can imagine this made me look in my 
organization.  Don't do the upgrade.

Vitali,

Fair enough. I was trying to avoid wipe-and-restore, but I guess I  
could end up doing that anyway if something goes bad, plus the added  
time expense of a failed upgrade.

Thanks for the advice.

Andy.
