Can I recommend you add virtualisation to your todo list.  I use 
linux-vserver, but there are plenty other ideas out there.

It's just superb that later on you can migrate services between physical 
hardware with MUCH less hassle.  You can easily test upgrades in a 
sandbox first. etc

I personally split all the tasks into different virtual servers.  Right 
now I actually still have quite a few mail related services in a single 
vserver, but ideally you would split everything up and then later if you 
needed to upgrade a single service or move it to a new machine it would 
have minimal effect.

Your general process sounds about right though - I think it may be 
possible for you to preserve pop uidls, but see the wiki for more notes 
on that

Good luck
