upgrade an old installation

[replabrobin]

I am running a fairly old (1 year) installation of archlinuxarm on a sheevaplug using an SD card.

Can I just use sudo pacman -Syu in the running system and expect this to work?
I can of course make a complete backup of the SD card so I'm not worrying about losing stuff.

Also I suspect that the internal flash kernel/system is even more out of date.
Is there a way to upgrade that from the SD card or should I just live with that as a fallback?

Thanks to all the Arch and Arm gurus who work so hard on this stuff.

yeah, just make the sdcard backup first (use a pc to do that), then boot alarm using the sdcard and live upgrade it .

you will find that there are some upgrade problems, such as updating to pacman4 , filesystem: /etc/mtab exists in filesystem. Please search the forum and there is solution here already.
