Skype for Business Server 2019 require Windows Server 2016 and SQL 2016 as perquisites. In-place upgrade form Skype for Business 2015 is not possible, and you can only do a site by site migration from Lync 2013 or Skype for Business 2015.
Skype for Business 2019 is still available as standard edition version and I will install this version in my lab.
