Licensing Question: Migrating CM4x to CUCM6x

Unanswered Question
Sep 25th, 2008

Will be running DMA but wanted to know if I need 'new' DLUs for devices migrated. I've opened up a case with TAC and was adviced that I can migrate the (phone)license files BUT will have to place a new order for it. Not sure what he meant by it, does anyone have a clue?

Well, actually when you upgrade your system from 4.X to 5.x or 6.X it will give you all the DLU's that you need for whathever you have installed at the moment of the migration. Now after the upgrade you will need to buy new DLU's if you wish to install new phones, or new features that requires DLU's

Exactly my thoughts. Only 'new devices and features' of course - but not the old. Tried reaching out to TAC to clarify but to no avail.

Thanks for clearing that up!

Hi Eddie,

I think TAC is referring to the step where you apply for the permanent DLU License file after DMA has been completed;

Here is the License info for CCM 5.x and beyond;

Migrating from Cisco CallManager 4.0(x) to 6.0(x)

When you migrate from Cisco CallManager version 4.0(x) to 6.0(x), the licenses that are required for existing phones and existing Cisco CallManager nodes is calculated and an intermediate file (XML file) that contains these license counts will be generated during the Cisco CallManager migration process. These licenses are given free of cost because you are already using these phones for Cisco CallManager version 4.x. If you are provisioning new phones and nodes after migrating to Cisco CallManager 6.0(x), you need to paste the intermediate license file in the License Registration window on CCO.

Use the following procedure to register existing licenses and request for new licenses.


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.

...from previous page

From here;

Licenses Not Requiring a PAK

If you do not have a Product Authorization Key (PAK), please click here for available licenses. (use the please click here link)

Available licenses include Evaluation/Demo Licenses, Cisco ASA 3DES/AES, PIX Firewall 3DES/AES and DES Encryption, Cisco Services for IPS, and Cisco Unified Communications Manager Version Upgrade licenses.

Go to;

Voice Products

Then select;

Cisco Unified Communications Manager Device Upgrade License

Here is an overview of the previous info;

Watch out for the note detailed in Step #2 below;

Step 1 After you complete the Cisco Unified Communications Manager upgrade process, navigate to Cisco Unified CallManager Administration and choose System > Licensing > License File Upload.

The License File Upload window displays.

Step 2 Choose the license XML file from the Existing Files drop-down list, and click View File. The window refreshes and displays the information for the selected license. Copy all of the information in this file except the HTML tags. To copy the contents on this window, choose the appropriate text and choose Ctrl-C (Copy).

Step 3 Navigate to the License Registration web tool at

Step 4 Enter the MAC address of the Ethernet 0 NIC of the first node of the Cisco Unified Communications Manager cluster.

Step 5 In the text box that is provided, paste the license file contents that you copied in Step 2 by using the appropriate keyboard shortcuts, such as Ctrl-V.

Step 6 Enter a valid e-mail address and click Continue. A license file generates.

The system sends the license file to you via e-mail using the e-mail address that you provided.

Step 7 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.

Step 8 You can obtain licenses for new devices that you are adding to the upgraded system, if your system requires additional device license units.

Have a look at this great tip from Jason;

"when you capture the xml file for the DLUS etc after the upgrade so that you can post it on Cisco's web site, it might be wrapped in HTML. ie the first line and the last line are html, and the license utility will reject it. Remove the first and last line to resolve this."

Hope this helps!
