Moving a Debian install in to new hardware?

["Jimmy Liang" <jimmy@skynetusa.com>]

Hi All,

I'm in need of some hints here. I have a P4 box running Debian 3.1, with
things like Postfix, spamassassin, MySQL, Apache, and other misc
softwares.
What I want to do is to move all that to a new box I have, with dual Xeon.
Can you suggest the best way to do this? I'd like to move it to a larger
drive, if possible, but its not critical.

1. I can do a new install on the Xeon, and migrate the content one by one,
but this is by far the slowest. Is there a way to extract the list of
packages I have on the P4, and have apt-get read that list to install?

2. If I simply take the drive and put it in the new box, can anyone think
of any problems? missing drivers and such? I don't know enough about the
Debian installer or the Linux kernel to know if they treat the P4 and Xeon
chips differently.

3. If and when I do need to exchange it for the larger drive, how would I
go about doing that without any reinstalls?

Thanks for any hints and ideas.
