Move from i686 to amd64 while keeping the data?
Posted by PaulePanter on Fri 11 Apr 2008 at 14:01
Dear readers,
as written in [1] I bought a new mainboard, processor and memory. My old computer is an Intel(R) Pentium(R) 4 CPU 2.40GHz, so i386/686. Since I have a software RAID1 and do not want to exchange, i. e., buy new, hard drives and keep my files (especially /home).
I am wondering: What is the best way to transition the system to the new mainboard (amd64)? I did not find anything useful with google.de right away.
I was thinking about doing the following.
1. Get the amd64 Debian installer.
2. Boot it in rescue mode and manuelly mount the encrypted partition with the LVM volumes.
3. Choose in the partition tool to format /, /boot and /usr (is that needed/enough?)
4. Install the base system and the boot loader.
5. Reboot.
6. Change the repository in /etc/apt/sources.list.
But if anyone has some suggestions or experience, it would be great to share it, so I can save myself a little trouble.
Thanks in advance,
Paul

Hi Julien, that post is pretty outdated, the guy even had to dist-upgrade to etch!
Nowadays is quite simple install etch for 64bits.
If PaulePanter have its data on separate partions --vg /home /var/www etc-- he'd to make a backup --this is important, Murphy exists-- and then install etch for amd64, formating whatever but data-partitions.

The AMD64 versions of Etch and Lenny are pretty complete, a few things are sill missing relative to i386, but overall it's not too painful if you do you preparation first accept that there will be a little manual intervention required.
Most data shouldn't care the bit size of the operating system. As long as your data is backed up (just in case), as Anonymous says, it shouldn't be a problem, installing AMD64 and keeping your home files. Scripts, email, images, video, audio and most documents are safe, the only thing would be any binaries that you compiled yourself - which would need recompiling.
I've been running Debian AMD64 since Sarge, when Etch came out several things got easier and Lenny (currently testing) things get easier again - though at the moment some bits in Etch currently don't have anything in Lenny yet but that is another story...

Thank you for your input.
The online shop (freexpress.de) sent me the wrong motherboard. So I still have some time to ask questions.
Should I format the /usr partition or is this not needed?
Thanks,
Paul
