upgrading server. confused :/

hey guys, this weekend i plan on upgrading my server from 32bit to 64bit.

i originally used an auto install oscam/cccam script for 32bit. but am now running oscam only with cccam protocol.

i have a dell optiplex 330 with interl core 2 duo that i have been meaning to use instead of my noisy 10+ year old 32bit machine.

when i am looking at the auto install scripts they reference AMD. will this work on the intel core duo?

also would i just start from fresh with an auto install script,set cccam port in oscam and swap my existing files over?

i am pretty confident with the dyndns setting etc etc. just confused on the actual upgrade.

ok, i will stick to 32bit. but will still need to change to the newer machine as the one i am using now sucks, its so load,

so would i just install auto in stall again and switch files over?
