Speaking from experience...you can upgrade, and it might even be preferable
to installing the system fresh. (Especially if you have a SB16 PnP sound
card, or possibly any PnP cards). I installed RH 5.2 some time ago. While
I am still on the lower end of the linux learning curve, I still pride
myself in knowing enough to get by. What I can't figure out I ask. I had
no problems installing RH5.2. And to be honest I didn't have much problems
installing Mandrake 6.1, except I couldn't get my sound card to work. It
all had to do with that stupid "isapnp.cong" file that sets up PnP cards at
boot up. It kept detecting conflicts with my card. (when infact none
exist!) I investigated the problem and discovered from the FAQ page that
no one knew why this happened, except that they suspected something to do
with the isapnp file and the 6.x build. So I ripped off. I was going to go
back to 5.2, and rebuild my kernel, and libraries manually. The idea really
didn't appeal to me. So in a last desparation effort, I installed 5.2, then
upgraded with Mandrake 6.1. The trick is though as someone mentioned
earlier, It won't upgrade everything. So think! Figure out what you need,
and manually select the packages. If you select something that needs
something you didn't select...don't sweat it. The install program will tell
you and ask you if it should install the packages!
I didn't mean to come across as an authority. I just am speaking from my
own experience. I hope this helps someone!
