It’s probably a good idea to delete the Avid Media database files (msmFMID.pmr and msmMMOB.mdb) from the OMFI directory on the Adrenaline machine. This will force the Adrenaline to re-index the media files and it should find the new stuff. I transfer projects between Xpress Pro machines and Xpress Pro and Adrenaline quite often. Move the files across, delete the database files and then load the Adrenaline. You should get a message saying ‘Indexing [drive]’.
I can also recommend MediaSift (www.senkou.com) for physically moving OMFI files around. I’m not sure if Media Mover is the same thing, but MediaSift works very well.
Hope you get it fixed.
