Media Composer does not have a true conform feature where a relink goes out and finds just the clips it needs. You will need to manage that manually. You can do a pull list, or make a list of the camera original file names that you will need to AMA link to (Link to in 8.4) first, to make them available to the project, then do a “relink to selected” as previously stated.
You can make an EDL to see which clips, or put the sequence into its own bin, and so a “set bin display” and “show reference clips” and you will see just the clips used to create the sequence. Sort by master clip, and you will see the files you need to go find that way.
