Hi Amr,
You will require new licenses when moving to CUE 7.4 but they
can be acquired for free (as shown below)
Beginning with Cisco Unity Express 7.1, a new type of license called CSL licensing is supported. With CSL licenses, the mailbox license count includes both personal mailboxes and GDMs. The type of the mailbox is determined when it is configured. Also, the call-agent is no longer specified using licenses and can be configured either as part of post-install process or during bootup.
Obtaining Migration Licenses
Note There is no cost to obtain migration licenses for CSL.
Required Information
To obtain CSL migration licenses you need to have the following information:
•The SKU for the features that you need.
This is the information that you determined in the "Selecting which Features You Want" section.
•The Product ID (PID)
•The Serial Number (SN) from the device.
Using the Migration Portal
Note You must have a CCO password to access some of the URLs in the following procedure.
Follow these steps to obtain a migration license for your existing Cisco Unity Express 7.1 features:
Step 1 Go to the licensing portal at www.cisco.com/go/license and click the link at the bottom of the page to go to the license migration portal.
Step 2 On the router that is running the features that you want to migrate, enter the show inventory command to see the corresponding product IDs and serial numbers.
Step 3 Enter the appropriate product ID and the serial number and click Continue.
The product ID is the type of Network Module that you are using, such as AIM-CUE.
Step 4 Use the drop-down menus to select the product family, product, and feature (SKU), then click Continue.
For the product, use the SKU that you determined in the previous section for the features that you want to migrate.
Enter your registration information, including your company's name and e-mail address, then click Continue.
Step 5 Verify all of your license information and click Submit to receive the free CSL upgrade license file by e-mail.
Step 6 Repeat the appropriate steps above for each device that is running features that you want to migrate.
Step 7 Copy the license file(s) to a FTP or TFTP server.
Adding More Mailboxes, Ports, IVR Sessions, and TimeCardView Users
When you buy licences for additional features on Cisco Unity Express 7.1, the licences are available only in the increments shown below. These licenses are the same for all supported devices. See the Release Notes for Cisco Unity Express 7.1 for a list of supported devices. The following types of licenses are available:
•Mailboxes (available only in increments of five)
•Ports (available only in increments of two)
•IVR (available only in increments of two)
•TimeCardView users (available only in increments of one)
The corresponding SKUs for these licenses are:
•FL-CUE-MBX-5
•FL-CUE-PORT-2
•FL-CUE-IVR-2
•FL-TCV-USER-1
To determine the total quantity of licenses you need, multiply the incremental quantity from the name of the CSL license with the explicit quantity of increments that you want to purchase. For instance, FL-CUE-MBX-5 represents an incremental quantity of five mailboxes. If you select an explicit quantity of four for the FL-CUE-MBX-5 feature, the total quantity will be five times four, or 20.
Using CLI Commands to Install Licenses
After you obtain a license file from Cisco's licensing portal and copy it to a FTP or TFTP server, use the following CLI commands to install the license. Only the use of FTP is shown below.
SUMMARY STEPS
1. license install ftp://username:password@ip_address/path/license_file
2. reload
3. enable
4. show license all
5. show license in-use
6. show license status application
