When I am doing an upgrade like that I like to start with a new machine so I can do an install while the old server is still on line. After hours I can move the user info to the new machine and swap them and have no perceived downtime. At the very least I use a different hard drive. These days with the price of hard drives under $100 for ide and just a few hundred a piece for each hot-swap scsi it is cheap to buy a new HD. That way I can swap drives and do the install over a weekend and guarantee that the client has a working server on Monday. If the server is not finished I just put in the old drives and the machine comes back up like it was on Friday. I only use ISP's who will give a subnet to my clients. That way I have extra IP's on the border to test a firewall before I put it into operation. -- Ed Weinberg
