Right now I'm running Vista Ultimate 32bit in bootcamp and am ready for a change. What I would ideally like to do is to switch over to Win7 64bit (in order to utilize my 4gb of ram) without having to reinstall all of my windows applications and games. Right now I'm really looking for the easiest and most efficient way of doing this (assuming it's possible to transfer between a 32 and 64bit operating system). What I had planned was to do things in this order: 1) Clone my bootcamp partition to my external hard drive using winclone. 2) Erase my bootcamp partition 3) Install Win7 to the bootcamp parition 4) Use the Windows Easy Transfer tool to migrate all of my vista files from the external hard drive over to Win7 5) Hopefully enjoy a much improved OS with all my programs fully functional Please tell me if I have neglected something or if there are any potential problems along the way. If it maters I have an early 2008 Macbook Pro, 2.5ghz, 4gb ram, 8600m 512mb. Thanks.
