Well, I have an extra partition for my important files, like all that office things, the important files like gpg, rsa, mails and so on.
I symlinked them to my /home/directory/<right place>.
What you shouldn't is to use config files from another installation/second distribution or similar, that doesn't work or it will break soon or later, but it will, because this is debian sid/unstable and the library's are mostly different to other distributions like ubuntu, arch and so on.
Debian is a bit different, it is going its own way.
So color settings, behaviour and so on you have to calibrate again.
Now have fun with siduction, welcome!
