Nicolas is right, you can (at your own risk, of course) do a migration like this, so DON'T is not really the only option, and changing distros is NOT an option in most cases. Gentoo is perfectly capable of that. Change flags in make.conf for generic compatible ones, compile a new kernel (I used genkernel for the migration, and compiled a specific kernel for the new machine later), emerge -e world and transfer the system (I used rsync, and had to deal with some network issues), everything worked (after some fine tunning for the new hardware) for me. Sometimes the effort is worth, it was my case, YMMV. It takes a little while (for me, the migration itself took a Sunday afternoon, like 6 hours), but you can still use your system while emerge does its work, and while the new kernel compiles. Its less time than a normal install from the ground up (with the whole configuration process, X, Window Manager, etc). After the migration, change flags again, and let emerge do its magic, while you can keep working. PS: I kept my old system as a backup for a few weeks. PS2: I had an old Athlon XP 1.2GHz and migrated the whole system to a Core Duo 2.8GHz, as you may imagine, both machines were COMPLETELY different, but still I kept all my preferences, packages, files, all of it. An year before the migration, the Athlon XP was running a CHOST=i386 and I changed it to i686 with success. Gentoo is sometimes just magical. -- Daniel da Veiga
[gentoo-user] move instalation from one system to another one.
Hi,
My old laptop is dying. I'm going to move my gentoo installation to a new
one. The old one was an old Pentium-M and the new one is core due. I want to
to tar the root and boot and .. files from the old one to untar it to the
new one. I want to know, What packages needs to rebuild (with What flags?)
in the old one so that I would have a basic runable system in the new that I
can rebuild all the packages on the new system with the new FLAGS?
Did anyone do this in the past? Have anyone any experiences regarding this
issue? Any comments? suggestions?
This is my old laptop make.conf
CHOST=i686-pc-linux-gnu
CFLAGS=-march=pentium-m -O2 -pipe
CXXFLAGS=${CFLAGS}
MAKEOPTS=-j2
Best regards

Don't do it.
I think your kernel will only support the pentium-m and most of the
software also. So a emerge -e world would bee necessary.
Normal Gentoo Installations are highly optemized for the specific
hardware. That is the whole point about using gentoo.
so save your world file and then setup up gentoo fresh and new. Won't be
that long, as you now own a core 2 duo...

If you want such functionality, use Debian or Ubuntu.

Do you need to get the new laptop working asap? Eg. for work?
Is the new laptop 32 or 64 bit?
If you need the new laptop running asap, the sub-optimal but fast way is to
build all the modules you'll require for your new laptop on the old laptop then
copy the disk. Since they tend to only add CPU features and not take them away
as time goes on, its worth a try as it will be a lot faster. You can then worry
about changing CFLAGs and rebuilding if you like, or just change the CFLAGs and
let anything new get built with them. No big deal.
If your system is 64 bit and you want to later run 64 bit OS you'll have to
reinstall.
For CFLAGs http://gentoo-wiki.com/Safe_Cflags, and you'll need to change CHOST
if you're going 64 bit.
