HP Quality Center 10.0x Obsolescence

I've received the letter from HP saying

 

“Hewlett-Packard (HP) is announcing the version discontinuance of HP Quality Center 10.0x. All customers with an active support contract for the above product are entitled to upgrade to HP Quality Center 11.x.”

 

Can anyone tell me if there is a cost associated with this upgrade please?  We have an active support contract.

 

Thanks,
