Depends really. I chose a CVSUP, followed by a make world and installed the new stuff in /etc (from /usr/src/etc) by hand, checking each file carefully. I then rebuilt the kernel and rebooted. This was mainly because the server currently supports 128 virtual web servers and another hundred sites under it's main IP address. I didn't fancy having much down time. The machine was previously running RELENG_2_1_0, which at the time was 2.1.7.1. I used CVsup to update to RELENG_2_2 and did a make world. One thing to be careful of is that the 'make world' can make so of the old libraries either non-functional, or disappear altogether, and so it's a good idea to make a copy of /usr/lib before you start. If whilst you're building the system any running process complains that it can't find a particular library you can suspend the make and run 'ldconfig', (or run it in another window). This will make the operating system update its idea of which libraries are available. If the library it's looking for doesn't exist in /usr/lib anymore you can copy it in before running the ldconfig. (In my case on another machine libgnumalloc went missing, and the running process was linked against it.) One last thing. As the make world replaces the libraries, you'll find things like 'ps' and 'top' stop working. I think that this is because the internal structure of the process tables have changed between releases. When I installed the new kernel and rebooted everything was fixed. I tell you because it can be a bit of a panic inducer finding that you can't see what's going on. Other than that it didn't seem to cause any major problems with the processes that were running at the time. Good luck. Let me know if you need anything.
