I bought an i5-3570k CPU and an Intel DH77DF motherboard and memory and I was wondering if I can swap them in for my Core 2 Duo system and have Ubuntu 10.04 still work (keeping the hard drives). Before the swap them in I was thinking of changing the video driver to Vesa (or can I just remove the xorg.conf file) and making sure I plug my hard drives in the correct order on the new motherboard. Does anyone know if this will work? Any other things I might have to do?
I would recommend upgrading to 12.04 first. The newer libraries, drivers, and kernel in 12.04 have better support for the newer hardware. You can just move the xorg.conf out of the way, and keep it as a backup. It shouldn't be needed. But it is good to keep it as a backup, in case you need to plug your hard drives into the old hardware and boot there, because you find it isn't working well on the new hardware.
