upgrading to 9.2 question

ok, my 9.2 CD's just came in the mail !!!!!!!!!!!!! and Amazon said Nov 15th was the ship date, they lied!! ok, when I installed 9.1 I just made a root and swap partition. I'd like to make a separate /home partition. I don't want to lose my current /home/users setup, so what's the best/easiest way to add a new /home partition?? shouldI add it first before I upgrade? or copy ( backup?) the /home directory to another partition, and add it during the uprade????? -- Paul Cartwright Registered Linux user # 367800
