[bitfolk] Lenny-to-Squeeze Upgrade Plan - 2nd opinions sought!

Hi everyone, I have decided to venture down what I hope is a well trodden path by now; upgrading my VPS from Debian Lenny to Squeeze. I have scoured the list archives and tried to make the most of http://www.debian.org/releases/squeeze/i386/release-notes/ch-upgrading.en.h… however I'm not ashamed to admit that I'm no expert in this regard and very much still learning so would appreciate a critique of my plan of action: - Ask Support kindly to perform a temporary disk snapshot - Login via Xen console - Verify no pending actions required for currently installed packages: aptitude (Then hit 'g' once in 'visual mode') - Verify that all packages are in an upgradable state: dpkg --audit - Show currently installed kernel(s): dpkg -l | grep linux-image Mine currently shows: ii linux-image-2.6-xen-686 2.6.26+17+lenny1 Linux 2.6 image on i686, oldstyle Xen suppor ii linux-image-2.6.26-1-xen-686 2.6.26-13lenny2 Linux 2.6.26 image on i686, oldstyle Xen sup ii linux-image-2.6.26-2-xen-686 2.6.26-26lenny2 Linux 2.6.26 image on i686, oldstyle Xen sup - Confirm non-usage of grub2: dpkg -l | grep grub Mine currently shows: ii grub 0.97-47lenny2 GRand Unified Bootloader (Legacy version) ii grub-common 1.96+20080724-16 GRand Unified Bootloader, version 2 (common - Updates apt sources lists from lenny to squeeze: sed -i s/lenny/squeeze/g /etc/apt/sources.list - Manually edit /etc/apt/source.list to confirm success of the above step and comment out any other repositories (non-Debian, backports etc) ? - Upgrade the kernel: (*** Am I aiming for the right one here? ***) aptitude install linux-image-2.6-686-bigmem - Update grub configuration: update-grub - Remove clocksource=jiffies from kopt directive in /boot/grub/menu.lst and confirm correct kernel will be loaded (i.e. default # matches new kernel position) - Upgrade udev (to minimise the risk of running the old udev with the new kernel): apt-get install udev - Reboot - Record a transcript of the upgrade session: script -t 2>~/upgrade-squeeze.time -a ~/upgrade-squeeze.script (This can be reviewed at a later date with scriptreplay ~/upgrade-squeeze.time ~/upgrade-squeeze.script) - Update the package list: apt-get update - Perform a minimal upgrade (i.e. upgrade those packages that don't require installation/removal of any other package(s)): apt-get upgrade - Complete the rest of the upgrade: apt-get dist-upgrade - Remove old/obsolete packages no longer required: apt-get autoremove - (Hopefully:) After the dust settles, advise Support that the snapshot of the old system can be removed Hope does that all look? Please don't hold back... Regards, Mathew
