My customer will change his Call Manager version from 6.1.4 to 7.1.3. The cluster (and phones) use security on phone.
I want to know if it is necessary to uninstall security before upgrade ? Could you give the documentation on the Cisco Web site ?
Thanks you for your help.
Unless you're changing the IP/hostname or adding servers to the cluster there is nothing special to do, just follow the regular upgrade instructions.
If you're doing any of the items i mentioned then you do need to turn security off, recreate the CTLs after upgrade and then reenable it.
If this helps, please rate
