Hosting teamsite content on VAP

ruler

Hello folks,

We are trying to research ways to host interwoven teamsite 6.5 content on the vignette application portal 4.5
Has anyone done such a thing. I have worked on interwoven but donot know much about vignette.
Can anyone share a few thoughts about how this can be done. What kind of problems
may we run into etc.
Any kind of documentation will be useful as well.
