Welcome to the Q&A Forum

I just found another copy of my old website and have no way to take it down.  Unfortunately, it's ranking so he didn't place it as a nofollow.  (My boss hired someone to redevelop our website before I came on board and never finished the project). So, could this be hurting us?  I tried to look to see if we were being penalized and couldn't find that we were. Also, ever since we migrated to a new domain name,  our ranking is tumbling.  I've redirected properly and tested to make sure they're resolving correctly and they are.  I have no idea what is going on.  We've virtually lost all ranking.  Any help would be much appreciated.
