    What is the easiest way of upgrading from Ubuntu 9.10 Karmic Koala 32-bit to Ubuntu 9.10 Karmic Koala 64-bit ?

    AFAIK, its not possible to upgrade form 32bit to 64bit. apt-get doesn't have multiarch support capability and it won't upgrade to another architecture.
    It is amazing what you can accomplish if you do not care who gets the credit.

    Thanks.
    I agree that you need to do a fresh intall and be done with it. You can restore any of your backed up data to the new system after the install.

    Have fun with 64-bit Linux!

    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    FWIW, benchmarks for current Linux systems show that generally a 64-bit OS will perform better than the same 32-bit one on the same x86_64 hardware. At least that's what I saw looking at a recent comparison of the latest 32-bit BSD with 32-bit Debian, and 64-bit BSD with 64-bit Debian systems. Generally, not universally, the 64-bit Debian was significantly faster performing in both CPU and disc-based benchmarks when run on the same physical hardware.
    Sometimes, real fast is almost as good as real time.
