importing data into Intralink

I have ~3000 files that I want to import into Intralink.  ~1400 of these files already exist in Commonspace.

Any advice on how to proceed?

Ideally, I'd like to avoid checking out the existing data and then importing again.

I haven't done this before.  Was wondering if I could create a new vault or context to import this data.

Any help would be appreciated.

Thanks.
