Few days back I've installed Lubuntu 12.10 x84 version. It was going ok, but I've realised that my CPU can handle 64-bit version of the OS.
So the question is - can I (if yes, how? I'm rather new Linux user) upgrade mu Luubntu to 64-bit version without loosing my data?
I've tried to find something on the Internet and this forum, but no luck. I'll be gratefull for every hint and reply!
