Honestly, rather than 3.0 to 4.0, I would look at the 3.0 to 4.5 move. ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Luchette, Jon Sent: Thursday, April 05, 2007 12:55 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] PS 3 to 4 Can anybody help me list out the major improvements that were made from Presentation Server 3.0 to 4.0 or the major differences between the two? The one that sticks out in my mind is the printing improvements (EMF) Also, anything to watch out for when upgrading or migrating from 3 to 4 would be greatly appreciated. Thanks! -Jon
