I've been studying
http://wiki.contribs.org/SME_Server_8#Upgrade_paths and various forum posts before upgrading our server, and I have a few questions - probably silly, but I prefer to be safe.
We have a system with 2 identical 1.5T disks. We don't want to change the hardware. As I understand it, the safest way is to use a CD, and remove one of the disks before doing the upgrade. I'll also be doing a full Workstation backup before I start.
(1) We have a few contribs, and I understand that I should remove them before starting. What's the best way to do that?
(2) In the upgrade document, there's a short section on upgrading with a CD, and a longer section on upgrading with Yum. I'm intending to use the CD method, and it's not clear to me how much of what follows is relevant - where does the "Yum only" bit finish, and the bit to be read by everyone start again? For example, is the stuff about upgrading Samba relevant to everyone? I get the impression it's only for people using betas..
(3) If I remove one disk before upgrading, and replace it afterwards, does SMEServer know which one to sync? Could it end up reversing my upgrade?
