Migrating to new server

Ok here is what I have. I am currently running Plex from a Terra-Master NAS. Obviously it's not truly powerful enough and I get some playback issues. The plan is to install Plex on a ZimaBlade 7700 which has an Intel Celeron processor. Question is when I install Plex on the ZimaBlade will I be able to add the current existing file locations on the Terra-Master to the new library on the ZimaBlade? I'm not worried about Metadata I can fix that.
