[one-users] Default how to convert "ubuntu 10.04 32 bits desktop" to "ubuntu 12.04 64 bits server"?

Normally this is possible to do the other way around (server to desktop). I definitely don't think a pre-built 32bit distro can be changed just like that into 64bits.

The only options you have here (if you still want to "change" desktop to server 32bits) is to boot into runlevel3 (text only; no X server) or just uninstall ubuntu-deskop.

It would be a lot easier if you start with a server image (ubuntu sever) and you install the packages you want.

Dear opennebula community,

how to convert "ubuntu 10.04 32 bits desktop" to "ubuntu 12.04 64 bits server" (after the conversion, the GUI desktop will be still available)?

i have a 64 bits server (support virtualization) with "ubuntu 10.04 32 bits desktop" installed. there are wine, filezilla, openoffice, oracle vm virtualbox etc applications, and some VM OS images installed in this server as well.

now i want to convert the "ubuntu 10.04 32 bits desktop" to "ubuntu 12.04 64 bits server", and require the above installed applications and VM OS images still work after the conversion. can this be achieved without any hassles? if yes, how to achieve it and what is the easiest way to do it? if the above installed applications not working after the conversion, could them work after being adjustified/reinstalled/tuned?

what i plan to do is to directly upgrade from "ubuntu 10.04 32 bits desktop" to "ubuntu 12.04 64 bits server", with a burned "ubuntu 12.04 64 bits server" CD. is this ok? otherwise, please advice.

thanks,
david su
