Did a bb "rename" but still finding some old host data

I recently used the bb "rename" command to rename a host that had switched usernames. Everything worked as expected, all of the trending data shows up under the new hostname.

However, I can run "find" in the data directory, and under data/hostdata/ I still see the old hostname directory, with 40MB of data files in it. Also, there is no directory for the newly renamed host. The files appear to be the full client output data.

Did the files not get properly moved? Should I now manually rename that directory, or are they linked to it and I should leave it alone?
