Renewing License with SEPSBE

Last year, I purchased 34 seats of SEPSBE for the computers and servers in our foundation through Tech Soup. The license will expire soon, so I need to renew the license. If I go back to Tech Soup and purchase another 34 seats, will they come with a single license file that I can just install on the server where the SEPM is running? In other words, I won't have to do anything with the clients like re-install the software, right? This will be the first time I will have to do this and I'm just unclear about the process.

Thanks in advance -
