Failed to magrating 7940 ip phones between 2 clusters remotely

[Qiyu Bao]

Just failed to magrating 7940 ip phones between 2 cluster yesterday

Some information of 2 clusters

Cluster A has just been upgraded from 6.1.2 to 8.6.2-21900 , and Cluster B upgraded from 8.5.1 to 8.6.2- 21900.

Cluster A used for the Shanghai Office , Cluster B used for others cities

We planned to magrate about 40 7940 iphones and 100 6921 iphones registered in Cluster A to Cluster B  but finally failed.

following is what we had done .

1  changed "PREPARE CLUSTER FOR ROLLBACK TO PRE 8.0 “ from false to true  in CUCM A

2  restarted TVS and TFTP service

3  reset those  iphones

4   change the DHCP settings on the remote SWITCH

as the result ,  all 6921  IP phones  successfully magrated between 2 clusters but 7940 failed

Is there any mistakes we made  or some other points we should take attention??

Hi,

You can find video in below post for deleting CTL file

If you do not have CTl file. You can reset your ip phone to factory default and register to new CUCM cluster.
