Migrate Skype for Business standard to Enterprise Pool

Hi Sokneang Sam There is no direct upgrade path from Std edition to Enterprise, What you can do is create a new enterprise pool in the same topology and you maybe able to move users from Std to enterprise pool. when you move them the external webservices URL will however change for these users and will now be the external webservices URL of the enterprise pool. Best option in my opinion would be to set up an enterprise pool and create a new test user in this pool, make sure everything works for him and if it does then you should just be able to move users from STD edition pool to Enterprise. Might be good to wait and see if anyone else has any better ideas.
