I don't know if a binary upgrade from i386 to amd64 is even possible, but I am fairly certain it is not supported. Source upgrades from i386 to amd64 are possible, but not trivial and not recommended. The recommended procedure for changing from i386 to amd64 is to make a backup of all important data on the machine, and then do a fresh install of amd64 after which any needed data is restored from the backup. -- Erik Trulsson ertr1013@student.uu.se
