Questions about the 64 bit and portable versions

[Jon Polish]

1. If I install the 64 bit version on a computer with an installed 32 bit version of version 5, will it also use the preferences from version 5? I will be installing 6 in the Program Files folder, not the Program Files (x86) folder where version 5 is installed. After installing version 6, can I uninstall 5 without the loss of my settings and customization? Actually, I should just ask, what is the best practice for installing version 6 in order to retain previous settings and customization from version 5?

2. How do I apply existing settings and customization from version 5 (installed) to a portable install of version 6 on a USB?

Thanks.
