It is always worth to get away from pentium 1 compiled package, use 8
general purpose registers and no memory pages, instead of the very old
system in 32 bits.

You can keep your /home if there's only data there, but I have to warn
you that you will NOT be able to use a 32 bits mysql /var/lib/mysql
folder on a 64 bits system. You WILL have to use mysqldump and then
reimport.
Anyway, you are right, the Debian installer can see your RAID and LVM
devices and not reformat them if you ask correctly.
