So your customer is best advised to use the 4.x branch, and indeed at the moment that is 4.10 (and the patches afterwards ofcourse). Furthermore, the advice is to upgrade to a very recent 4.x first, before taking the step to 5.x. So you´ll probably want to upgrade to 4.10p2 or 4-STABLE anyway. Maybe your customer would like you to go for an updated 4.x first, and go to 5.x later when it will be STABLE.

Re: upgrading form 4.2 to 5.x
Conventional wisdom is that upgrading over major versions is an interesting academic exercise and an a great display of the power and flexibility of the platform, but that if you're just trying to get a working system then a clean install is the preferred method. With good separation of system, application and data, it shouldn't be difficult. -Andrew- -- ___ | -Andrew J.

So your customer is best advised to use the 4.x branch, and indeed at the moment that is 4.10 (and the patches afterwards ofcourse). However i am running FreeBSD 5.x as production server in 2 colocated boxes without any problems. So it does not mean that it's crashing all the time, but there might be bugs that can cause downtime for your customer, and he should be willing to risk that problem if you want to upgrade to 5.x. If he prefers stablitity, and little downtime you do best to upgrade to the latest 4 release with patches. Since it's a very long while back that i runned 4.x (4.3 ...) i can't remember anymore what the huge differences are, perhaps someone else can describe that to you.

I have gone this route a couple of times. It was an interesting exercise, but not one I would recommend. It works, but things like the transition from ufs to ufs2 and new threading libraries and LOTS more make it a rough way to go. I think the advise to do a fresh install is the best option if you go to 5, but I'd really recommend staying at 4.10 or STABLE for now. -- R.
