I am currently on Debian Squeeze 32 bit and I want to install Wheezy 64 bit, preserving my /home partition

I know that compiled files will not work unless configuring multiarch, but can I find other issues?

I'm specially concerned about evolution and iceweasel files

Don't worry, configuration files are architecture indipendent; I've upgraded a similar system some weeks ago: it works flawlessy

great! do you know what happens with sqlite database files? – tictacbum Mar 4 '13 at 13:05
here says sqlite databases are not affected: – tictacbum Mar 4 '13 at 13:25
sqlite files too are arch-indipendent (firefox history file is a sqlite file, e.g.) – Andrea de Palo Mar 5 '13 at 6:54

It should work fine. If you have installed binary programs in your home directory e.g. in a /home/user1/bin/ directory, which some users occasionally do then obviously you would have to upgrade that directory as well. Life will be easier since you said you kept a separate /home partition.
