Phones 7961 will not registered corect after cucm upgrade

Hello,

we migrate a non secure cluster version 6.1.5 to 9.1.2. After the upgrade we change the Hostname and the IPs of the system. 7940/60 Phones are registered fine on the new cluster. Phone 7941/61 loads the new FW and the new Locals but the phones will not registered. The cucm reject the phones. The strange part is that we can reset the phone from the cucm and we can use the directory search on the phone.

Have anybody also in the past the problem and a solution for our problem?

thx for help
