Hi

You will need another license for the server.

hi , 

thanks Ed , 

yes we need Exchange License for the new server ,  my question is do i need CAL License as well ?

Thanks 

Hi JavaHeart,

Base on my knowledge, a CAL (Client access license) is required for each user or device that accesses the server software.

If you have purchased CAL before, you need not to purchase again.
