I have been working with the migrations for a few weeks and I understand the process of using the Call Manager Upgrade Utility for a health check and the DMA tool to create the tar ball of configuration info for import into the 6.0 install. My question lies with the DLU migration. The first time I migrated no DLU's followed and I couldn't use my phones (I did have a cluster node lic).
I then read where you can go to http://www.cisco.com/go/license and click on "here for available licenses". You can choose "Cisco CallManager Device Upgrade License". Then it asks you to "Please cut and paste the information from the file generated by your Cisco CallManager Upgrade Utility below:*" along with the mac of the server nic. My question is WHERE DO I FIND THIS FILE??
I saw one doc that said that the Cisco upgrade utility generates it but I couldn't find it. Help!!!! :)
Here is the method;
Step 1 In Cisco CallManager Administration, choose System > Licensing > License File Upload.
The License File Upload window displays.
Step 2 Click View File. A pop-up window displays that has the license information for existing phones and nodes. Copy this information. To copy the contents on this windrow, you can use Ctrl-A (Select All) and Ctrl-C (Copy).
Step 3 On the License Registration window of CCO website, in the text box provided, paste the file contents using Ctrl-V.
Step 4 You must enter the MAC address of the Cisco CallManager server that you are requesting the licenses for, and a valid E-mail Id.
Step 5 To obtain the actual license file, click Submit. A license file is generated.
Step 6 You must upload the license file to the server with the matching MAC address that you provided in Step 4. See the "Uploading a License file" section in the Cisco CallManager Administration Guide. This node takes on the functionality of the license manager.
Hope this helps!
EDIT: You have trumped me again Mahesh, my lack of typing skills is displayed again :)
