Scaling up SEPM for more Endpoints

Hi All,

          I think this is an easy question for you and I hope you can give me an idea of which way to go. The company I work for has been aquired by a larger concern and there is a big possibility that it would also like to use SEP as its desktop AV. I currently have 2 SEPM's located in a datacenter and they service 13,500 endpoints worldwide. I have a good GUP structure setup as well. The number of Endpoints will increase to 35,000 - possibly. I want to keep my structure at the simplist level. Will the 2 SEPM's I have be able to manage the extra Endpoints together with an increased GUP structure? It will the latest 12.1.6 MP1a software. As usual any advice help will be geatly appreciated.

Cheers
