I considering doing a complete re-build of my home desktop computer. The only thing that will actually be the same, will be the case. I have a 1 TB external hard drive I want to back up my 200 GB of stuff to. I want to basically be able to "clone" this entire system onto a bigger hard drive of a compltelely different system, with faster CPU, better motherboard, and alot more memory (more than 4 Gigs). The issues are that I am running the 32 bit version of Elementary OS Jupiter, but to have more than 4 gigs of memory, I know you need 64 bit. So I don't think a direct clone would really work. Is there any way to backup all my apps, files, settings, and even my themes and backgrounds from this 32 bit system. And restore them to a new install of a 64 bit system?
Also eOS Jupiter is based on Ubuntu 10.10. I really really don't like how Unity and Gnome 3 are looking right now. Theme wise and system wise. So sticking with eOS Jupiter for now would be very perferable.
