Linking existing citation in a document with EndNote Library?

Hi!

I’ll be giving a training on EndNote and the attendees already ask me how to link existing references in a Word document with their new EndNote library.

They previously used Reference Managers and references have been imported in a EndNote library.

Is it possible to link references from old documents with this new library??

If yes, how to do it?

Thanks a lot for your feed-back,

Véronique

did you see this PDF

http://endnote.com/sites/en/files/m/pdf/Reference_Manager_Conversion_instructions.pdf 

(and I think there is a youtube video too) 

(I googled the words “refman document to endnote” (no quotes)  

On a PC the convert command is from the ribbon, convert dropdown (as shown in the attached image).  On a Mac, I think the convert commands are under the bibliography dropdown dialogue.
