Reply to Traktor - moving library from older version to newer version?

I upgraded to Traktor 2.6 a while ago then decided I didn't like it, so since then I've been using... whatever the version before that was, 2,5 I guess... by accessing it from the 'backup' folder in the Traktor folder on my start menu. However, I've decided I want to move to 2.6 now, but is there a way to 'import' all my library tracks that I've added to me 2.5 library to my 2.6 library? You know, that thing when you first start a new version that offers to import all your tracks and playlists and stuff. Because I've got a fair few tracks that I added to my 2.5 library since installing 2.6 that I want in my 2.6 library but it's a pain to add them automatically.

I just can't seem to find the right option to start the process. Cheers!
