I have a server setup in my closet, that for some reason installed the 32-bit version of Ubuntu 10.04 instead of the 64-bit. My server has 6 gigs of RAM but is only using 2 gigs. I would like to upgrade from 32 to 64 bit without losing anything. Is that possible at all?
If not, is there a way you suggest so that I can backup all my documents and setups so I don't have to set it all up again? I have a website, ftp, and all kinds of important programs on there that I took forever to setup. I would not like to lose any of it...
