Hi Saeed,
You can use the same LAC which u got from Cisco but u need to have fresh registration key which u get after installing Attendnact application from HElp--Licensing .Further, u need to have re-host of licenses if u do any of below changes:
If you do any of the following to the server environment you must re-license the software with a new
Registration code:
• Reinstall the operating system on the same hardware
• Install a different operating system on the same hardware
• Add or remove certain hardware (such as an NIC card)
• Install the software on different hardware
• Install a different operating system
• Perform a major upgrade of Attendant Application.
And within a VM environment: copy a VM image.
regds,
