[arch-general] arch32 -> arch64 migration without reinstalling
Since I've already got a 32bit laptop, I was thinking of migrating my Core 2 Duo to arch64 (as a TU it would be really helpful for building new packages and helping the other packagers). Now, this desktop is my main system, so I'm not really happy with the idea of reinstalling and reconfiguring everything (given that, at this time, I have more than 1700 installed packages). So here's the idea: is it crazy to dump the package list, boot from a cd, change my mirrors in x86_64, change pacman's installation root to my mounted disks, reinstall the world and then check for *.pac*? Is there any risk I can't see in doing this? Thanks, Corrado

well i would recommend save the list of packages you have and don't format your /home partition, then start with new x86_64 else it's weird i think. I did it that way and works fine(hey installing arch works in 15 minutes doesn't it? ;) ). You could also save your existing 686 as a chroot if you have the space to safe it. greetings tpowa -- Tobias Powalowski Archlinux Developer & Package Maintainer (tpowa) http://www.archlinux.org tpowa@archlinux.org

I know it's weird. Otherwise I wouldn't have asked :)

Yes, it does. It's reconfiguring it from the ground up that takes a lot of time. Also, what if I left my files around in some forgotten place (and I'm pretty sure I did)? Should I run a pacman -Qo on everything? =) I know it would be better to reorganize everything and clean things, I just don't have the time to do it. Corrado

I would use (q)parted to create an extra 5Gb to 10Gb partition and install a 64bit AL into it and simply mount the same /home partition. Just add the 64bit partition /boot/* files to the current 32bit menu.lst and dual boot. Take your time to tweak the new 64bit world and be able to drop back to your old 32bit system if need be and/or use it as a chroot to run some 32bit apps from the new 64bit world anyway. --markc
