I've upgraded both 5.x to 6.x without serious problems, or even much work. The usual advice holds: a serial console is invaluable, especially when working remotely. You're much more likely to run into application upgrade problems when you rebuild them all (or do binary updates), so you might consider updating all your applications first using portupgrade so that you can separate the issue of upgrading applications and OS. You'll have to immediately rebuild the apps again after the OS upgrade, but it will be a rebuild of the same version of an app, rather than sliding version numbers. Do make sure to boot a 6.x kernel with your 5.x userland and test things out a bit - make sure your hardware probes, is reliable, etc. Robert N M Watson Computer Laboratory University of Cambridge
