[gentoo-user] Install Gentoo on one machine, then move the drive to another

[Jon M <gentoo@net-xero.net>]

Hey again everyone,

Here is my situation:

I have CentOS running on a system in a datacenter, but want to switch to 
Gentoo.  Basically what I've started to do is installed Gentoo on a P4 
3.0Ghz machine at home, and plan on moving it to a Pentium D 2.66Ghz. 
Now if I configure/compile/install all my software on the P4, and the 
kernel is configured for all the hardware in the other machine, will it 
magically work, or will it freak out?  My other concern is that maybe 
the applications won't be optimized for the other machine.  If this is 
the case, once it's down there, could I simply emerge all of my programs 
one at a time?

My reason for doing this is to minimize downtime.  I didn't want to take 
the server offline for a week while I take my time configuring a new 
setup.  This way it should only be down for maybe 5 minutes while I do a 
hard drive swap.

Thanks in advance for anyones thoughts on this.
