I do believe you must do a fresh install to go to x86_64.  You've
already established a 32-bit environment, so any updates would be
32-bit.

A warning, however.  Many browser plugins (Flash, to name one) are not
available on x86_64.  I recommend you install the 32-bit
Firefox/Thunderbird/Mozilla so you can get the plugins.
