Hey list, I am getting to upgrade (woo-hoo!) from my crusty old -k7 box to a shiny new core2duo blah blah blah box. That means I get to move up to 64 bit. In keeping with my personal preference to *never* reinstall, I've got an opportunity to attempt to migrate a running system from 32 to 64 bit. I also have the opportunity to practice on my laptop which could run 64 bit but currently isn't. The laptop is really just a duplicate of my desktop machine in terms of data and apps, so it should be a fairly good test bed. I've done some preliminary research and found the following links: http://www.digitalkingdom.org/~rlpowell/hobbies/debian_arch_up/index.html claims it can be done if you follow the right steps, and it seems reasonable to me... though the blink tag does put the fear in me. But there is no date, and based on the versions of .deb listed appears to be rather out of date... then there is this: http://alioth.debian.org/docman/view.php/30192/21/debian-amd64-howto.html#id292796 which specifically says: No. You need to reinstall on a newly formatted partition or disk, by either running cdebootstrap / debootstrap from your running installation or using the Debian-Installer. when asked about upgrading a running system. But that was last updated in 2006... Most all else I've found addresses *running* 64 bits not migrating to it. So, I'm looking for pointers, horror/success stories etc... to guide me through this process. One particular concern, as far as the laptop goes, is whether I can migrate an encrypted luks partition from 32 to 64 bits. That whole system is encrypted except for /boot and the encrypted partitions are underneath lvm as well... hmmm... that could be sticky eh? I look forward to your advice. A --
