Can we have only one user in the entire organization with Smartsheet Advance Licence ?


We all knew that, the Workflows in DataShuttle would become unlimited with the Smartsheet advance. But right now if we try to get advance licence for only one user in the organisation and all other other users continue to have the enterprise licence, will there be any compatibility issue ??

So if there are 100 users in my organization using the enterprise Licence and I (the 101th user) try to get one single Advance Licence, is it mandatory that all the other 100 users too migrate to Advance licence or they can continue with the existing enterprise Licence ????
