Phone wont Register after CCM Upgrade 4.1 to 5.1.3

Hello, I just finished to upgrade from CCM 4.1 to 5.1.3 , I'm able to login into the web interface, I loaded the license and all of the configuration were migrated Successfully from the DMA. my problem is I can't get a phone to register, I manually setup the phone with ip address, tftp , route but the phone keeps on hanging saying registering. I checked the CTL logs, and they are on the phone, I even clean them but still the phone wont register. any idea? thanks.

The problem was that CTL was renamed on the publisher with an extension .NEW. Tac went in the root, changed the file extension and the phones registered right away.
