Importing Pitch Corrected Vocals into Older project

Song writing partner is also on Cubase 7.0.1
Her vocals have been pitch corrected, but when I use import track archive,
the pitch correction is not there. When I try to click pitch on, it re-analyzes the track.
If I open a brand new, clean project, the import works as it should.
I’ve tried erasing all the vocals from the older project, and then importing the track selects,
but again, the pitch correction disappears.
How can I import her new vocals into my project, which is full of MIDI tracks, instruments, in
a complete mix, and have her pitch correction come across?
Very frustrating.

Export the corrected track (set your locators to the start of the first bar, not the start of the vocals) and import the track into your other project
