Thanks everyone for comments. I'm writing this on my new laptop. I rebuilt the system on old laptop with CFLAGS=-march=i686 -O2 -pipe before the moving the binary to the new laptop. I've a usable but unstable Desktop on the new system. Some application like stella don't load and others crashing at random times. I'm sure the system will be stable when I recompile all the other packages with the new flags. Thanks anyone Platoali

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. Yeah, but that way you're doing emerge -e world twice. One on the old system, and one on the new system (to optimize for the specific CPU again; -march=native). It's usually faster to install from scratch and only transfer your setting to the new system.

It's usually faster to install from scratch and only transfer your setting to the new system. Yes, but still, both emerges may run while you work, so that's not wasted time, while on a new install, your machine is useless till you get all that you need running (that's the compilation time for X, an office suite, a window manager), and after that, you gotta transfer all your files and settings (that may be tedious), and all of this takes a time you could use to work... All I'm saying is that you really don't need to start from scratch, I personally find it more productive and fast (not to mention less boring) to prepare and transfer the whole install, and only configure the new hardware (that is part of a normal new install, so, you can't avoid that), instead of waiting for compilations to end so you can use packages on your new machine. Besides, I'm letting the official portage tool do its job... Anyway, it is MHO. In some cases, this may fail and a install from scratch is the only option left. But I never had this bad luck. -- Daniel da Veiga

Gentoo is perfectly capable of that. Thanks to you. You explained my thoughts better than I could. 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.

It's usually faster to install from scratch and only transfer your setting to the new system. You are right too. IMHO, a new install is what you have to do for a such occasionally hardware upgrade. Note the emerge -e world is not what we need here as it will leave broken system packages (the system won't boot on the new processor). The '-e' option looks for the USE flags only. We are supposed to know what we do with Gentoo. Having hardware specific options makes the distribution in a possibly jail. Nevertheless, Gentoo and Linux offer all generic options to ensure x86 processor-like migrations. -- Nicolas Sebrecht
